They are much dimmer and rarer than solar rainbows, requiring the Moon to be near-full in order for them to be seen. For the same reason, moonbows are often perceived as white and may be thought of as monochrome.

The full spectrum is present, however, but the human eye is not normally sensitive enough to see the colours. Long exposure photographs will sometimes show the colour in this type of rainbow.

Fogbows form in the same way as rainbows, but they are formed by much smaller cloud and fog droplets that diffract light extensively.

They are almost white with faint reds on the outside and blues inside; often one or more broad supernumerary bands can be discerned inside the inner edge.

The colours are dim because the bow in each colour is very broad and the colours overlap. Fogbows are commonly seen over water when air in contact with the cooler water is chilled, but they can be found anywhere if the fog is thin enough for the sun to shine through and the sun is fairly bright.

They are very large—almost as big as a rainbow and much broader. They sometimes appear with a glory at the bow's centre.

Fog bows should not be confused with ice halos , which are very common around the world and visible much more often than rainbows of any order , [57] yet are unrelated to rainbows.

The circumzenithal and circumhorizontal arcs are two related optical phenomena similar in appearance to a rainbow, but unlike the latter, their origin lies in light refraction through hexagonal ice crystals rather than liquid water droplets.

This means that they are not rainbows, but members of the large family of halos. Both arcs are brightly coloured ring segments centred on the zenith , but in different positions in the sky: The circumzenithal arc is notably curved and located high above the Sun or Moon with its convex side pointing downwards creating the impression of an "upside down rainbow" ; the circumhorizontal arc runs much closer to the horizon, is more straight and located at a significant distance below the Sun or Moon.

Both arcs have their red side pointing towards the sun and their violet part away from it, meaning the circumzenithal arc is red on the bottom, while the circumhorizontal arc is red on top.

The circumhorizontal arc is sometimes referred to by the misnomer "fire rainbow". It has been suggested that rainbows might exist on Saturn 's moon Titan , as it has a wet surface and humid clouds.

Although visible rainbows may be rare due to Titan's hazy skies , infrared rainbows may be more common, but an observer would need infrared night vision goggles to see them.

Droplets or spheres composed of materials with different refractive indices than plain water produce rainbows with different radius angles.

Since salt water has a higher refractive index, a sea spray bow doesn't perfectly align with the ordinary rainbow, if seen at the same spot.

Due to a much higher refractive index, rainbows observed on such marbles have a noticeably smaller radius. The displacement of the rainbow due to different refractive indices can be pushed to a peculiar limit.

For a material with a refractive index larger than 2, there is no angle fulfilling the requirements for the first order rainbow.

For example, the index of refraction of diamond is about 2. This results in a rainbow of the n -th order shrinking to the antisolar point and vanishing.

The classical Greek scholar Aristotle — BC was first to devote serious attention to the rainbow. Lee and Alistair B. Fraser, "Despite its many flaws and its appeal to Pythagorean numerology, Aristotle's qualitative explanation showed an inventiveness and relative consistency that was unmatched for centuries.

After Aristotle's death, much rainbow theory consisted of reaction to his work, although not all of this was uncritical.

In Book I of Naturales Quaestiones c. He notices that rainbows appear always opposite to the sun, that they appear in water sprayed by a rower, in the water spat by a fuller on clothes stretched on pegs or by water sprayed through a small hole in a burst pipe.

He even speaks of rainbows produced by small rods virgulae of glass, anticipating Newton's experiences with prisms.

He takes into account two theories: one, that the rainbow is produced by the sun reflecting in each water drop, the other, that it is produced by the sun reflected in a cloud shaped like a concave mirror ; he favours the latter.

He also discusses other phenomena related to rainbows: the mysterious "virgae" rods , halos and parhelia. According to Hüseyin Gazi Topdemir, the Arab physicist and polymath Ibn al-Haytham Alhazen; — , attempted to provide a scientific explanation for the rainbow phenomenon.

In his Maqala fi al-Hala wa Qaws Quzah On the Rainbow and Halo , al-Haytham "explained the formation of rainbow as an image, which forms at a concave mirror.

If the rays of light coming from a farther light source reflect to any point on axis of the concave mirror, they form concentric circles in that point.

When it is supposed that the sun as a farther light source, the eye of viewer as a point on the axis of mirror and a cloud as a reflecting surface, then it can be observed the concentric circles are forming on the axis.

The cloud, he thought, serves simply as the background of this thin substance, much as a quicksilver lining is placed upon the rear surface of the glass in a mirror.

In Song Dynasty China — , a polymath scholar-official named Shen Kuo — hypothesised—as a certain Sun Sikong — did before him—that rainbows were formed by a phenomenon of sunlight encountering droplets of rain in the air.

According to Nader El-Bizri, the Persian astronomer , Qutb al-Din al-Shirazi — , gave a fairly accurate explanation for the rainbow phenomenon.

He "proposed a model where the ray of light from the sun was refracted twice by a water droplet, one or more reflections occurring between the two refractions.

He then placed this model within a camera obscura that has a controlled aperture for the introduction of light. He projected light unto the sphere and ultimately deduced through several trials and detailed observations of reflections and refractions of light that the colours of the rainbow are phenomena of the decomposition of light.

His work on light was continued by Roger Bacon , who wrote in his Opus Majus of about experiments with light shining through crystals and water droplets showing the colours of the rainbow.

He explained the primary rainbow, noting that "when sunlight falls on individual drops of moisture, the rays undergo two refractions upon ingress and egress and one reflection at the back of the drop before transmission into the eye of the observer.

Descartes ' treatise, Discourse on Method , further advanced this explanation. Knowing that the size of raindrops did not appear to affect the observed rainbow, he experimented with passing rays of light through a large glass sphere filled with water.

By measuring the angles that the rays emerged, he concluded that the primary bow was caused by a single internal reflection inside the raindrop and that a secondary bow could be caused by two internal reflections.

He supported this conclusion with a derivation of the law of refraction subsequently to, but independently of, Snell and correctly calculated the angles for both bows.

His explanation of the colours, however, was based on a mechanical version of the traditional theory that colours were produced by a modification of white light.

Isaac Newton demonstrated that white light was composed of the light of all the colours of the rainbow, which a glass prism could separate into the full spectrum of colours, rejecting the theory that the colours were produced by a modification of white light.

He also showed that red light is refracted less than blue light, which led to the first scientific explanation of the major features of the rainbow.

Young's work was refined in the s by George Biddell Airy , who explained the dependence of the strength of the colours of the rainbow on the size of the water droplets.

For example, Nussenzveig provides a modern overview. Experiments on the rainbow phenomenon using artificial raindrops, i.

Later, also Descartes studied the phenomenon using a Florence flask. A flask experiment known as Florence's rainbow is still often used today as an imposing and intuitively accessible demonstration experiment of the rainbow phenomenon.

Due to the finite wall thickness and the macroscopic character of the artificial raindrop, several subtle differences exist as compared to the natural phenomenon, [85] [86] including slightly changed rainbow angles and a splitting of the rainbow orders.

A very similar experiment consists in using a cylindrical glass vessel filled with water or a solid transparent cylinder and illuminated either parallel to the circular base i.

Under these latter conditions the rainbow angles change relative to the natural phenomenon since the effective index of refraction of water changes Bravais' index of refraction for inclined rays applies.

Other experiments use small liquid drops, [52] [53] see text above. Rainbows occur frequently in mythology , and have been used in the arts.

One of the earliest literary occurrences of a rainbow is in the Book of Genesis chapter 9, as part of the flood story of Noah , where it is a sign of God's covenant to never destroy all life on earth with a global flood again.

In Norse mythology , the rainbow bridge Bifröst connects the world of men Midgard and the realm of the gods Asgard. Some forms of Tibetan Buddhism or Dzogchen reference a rainbow body.

This place is appropriately impossible to reach, because the rainbow is an optical effect which cannot be approached.

Rainbows appear in heraldry - in heraldry the rainbow proper consists of 4 bands of color Or , Gules , Vert , Argent with the ends resting on clouds.

Rainbow flags have been used for centuries. It was a symbol of the Cooperative movement in the German Peasants' War in the 16th century, of peace in Italy, and of gay pride and LGBT social movements since the s.

The rainbow has also been used in technology product logos, including the Apple computer logo. Many political alliances spanning multiple political parties have called themselves a " Rainbow Coalition ".

From Wikipedia, the free encyclopedia. For other uses, see Rainbow disambiguation. Light rays enter a raindrop from one direction typically a straight line from the sun , reflect off the back of the raindrop, and fan out as they leave the raindrop.

The light leaving the rainbow is spread over a wide angle, with a maximum intensity at the angles This diagram only shows the paths relevant to the rainbow.

White light separates into different colours on entering the raindrop due to dispersion, causing red light to be refracted less than blue light.

At the end of the book, having failed to find her fulfilment in Skrebensky, she has a vision of a rainbow towering over the Earth, promising a new dawn for humanity:.

Lawrence's frank treatment of sexual desire , and the part it plays within relationships as a natural and even spiritual force of life, caused The Rainbow to be prosecuted in an obscenity trial at Bow Street Magistrates' Court on 13 November , as a result of which 1, copies were seized and burnt.

The Rainbow was followed by a sequel in , Women in Love. Although Lawrence conceived of the two novels as one, considering the titles The Sisters and The Wedding Ring for the work, they were published as two separate novels at the urging of his publisher.

However, after the negative public reception of The Rainbow , Lawrence's publisher opted out of publishing the sequel. Ursula's spiritual and emotional quest continues in Women in Love , in which she continues to be a main character.

This second work follows her into a relationship with Rupert Birkin often seen as a self-portrait by Lawrence , and follows her sister Gudrun's parallel relationship with Birkin's friend, Gerald Crich.

The philosopher Roger Scruton argues in Sexual Desire that "because we live in a world structured by gender, the other sex is forever to some extent a mystery to us, with a dimension of experience that we can imagine but never inwardly know.

The following year, the novel was adapted into the UK film The Rainbow , directed by Ken Russell , who had also directed the film adaptation Women in Love.

In a laboratory setting, it is possible to create bows of much higher orders. Felix Billet — depicted angular positions up to the 19th-order rainbow, a pattern he called a "rose of rainbows".

Up to the th-order rainbow was reported by Ng et al. Tertiary and quaternary rainbows should not be confused with "triple" and "quadruple" rainbows—terms sometimes erroneously used to refer to the—much more common—supernumerary bows and reflection rainbows.
