It takes the form of a multicoloured circular arc. Indeed, it is impossible for an observer to see a rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the light source. All rights reserved.a bow or arc of prismatic colors appearing in the heavens opposite the sun and caused by the refraction and reflection of the sun's rays in drops of rain.a similar bow of colors, especially one appearing in the spray of a waterfall or fountain.He pursued the rainbow of a singing career for years before becoming a success.having a diverse membership; including representatives from multiple racial and ethnic groups: a bow-shaped display in the sky of the colours of the spectrum, caused by the refraction and reflection of the sun's rays through rain or mistof or relating to a political grouping together by several minorities, esp of different racesa member of the Rainbow Guides, the youngest group of girls (aged 5-7 years) in The Guide AssociationAn arc-shaped spectrum of color seen in the sky opposite the Sun, especially after rain, caused by the refraction and reflection of sunlight by droplets of water suspended in the air. Question Posted / sunilhunk86. While playing around with word vectors and the "HasProperty" API of conceptnet, I had a bit of fun trying to get the adjectives which commonly describe a word.
water-filled spherical flasks, go back at least to 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.e. ― E.Y. Up to eight separate bows may be distinguished if the reflected and reflection rainbows happen to occur simultaneously: The normal (non-reflection) primary and secondary bows above the horizon (1, 2) with their reflected counterparts below it (3, 4), and the reflection primary and secondary bows above the horizon (5, 6) with their reflected counterparts below it (7, 8).Occasionally a shower may happen at sunrise or sunset, where the shorter wavelengths like blue and green have been scattered and essentially removed from the spectrum. Like most atmospheric optical phenomena, rainbows can be caused by light from the Sun, but also from the Moon.
Somewhere over the rainbow, skies are blue, and the dreams that you dare to dream really do come true. Even if an observer sees another observer who seems "under" or "at the end of" a rainbow, the second observer will see a different rainbow—farther off—at the same angle as seen by the first observer. These include not only rain, but also mist, spray, and airborne Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind the observer at a low The rainbow effect is also commonly seen near waterfalls or fountains.
The rainbow is formed when water droplets in the air cause the Absentee Ballot vs. Mail-In Ballot: Is There A Difference?“Epidemic” vs. “Pandemic” vs. “Endemic”: What Do These Terms Mean?All Of These Words Are Offensive (But Only Sometimes)Don’t be verecund—we know you remember these popular words from July. ― Anonymous.

7 (2009), pp.
The light is The reason the returning light is most intense at about 42° is that this is a turning point – light hitting the outermost ring of the drop gets returned at less than 42°, as does the light hitting the drop nearer to its centre. They are almost white with faint reds on the outside and blues inside; often one or more broad Both arcs are brightly coloured ring segments centred on the It has been suggested that rainbows might exist on Droplets (or spheres) composed of materials with different refractive indices than plain water produce rainbows with different radius angles.
