what is rainbow?

Answer 1

Rainbows are optical and meteorological phenomena that cause a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arch and violet on the inner section of the arch. More rarely, a double rainbow is seen, which includes a second, fainter arc with colours in the opposite order, that is, with violet on the outside and red on the inside.

Even though a rainbow spans a continuous spectrum of colours, traditionally the full sequence of colours is most commonly cited and remembered as red, orange, yellow, green, blue, indigo and violet. ("Roy G. Biv" and "Richard Of York Gave Battle In Vain" are popular mnemonics.)

Though rainbows are bow-shaped in most cases, there are also phenomena of rainbow-coloured strips in the sky: in the shape of stripes, circles, or even flames. (See Circumhorizontal arc)

Answer 2

A bow caused by rain drops.The rain droplets act as prism which refract and reflect the sun's rays bringing all the colours to your eye so that you can see it as a rainbow provided the drops subtend a particular angle at your eye.

Answer 3

Rainbow is the true sunshine.Or you can think the sunshine is made of red,orange,yellow,green,blue,indigo,purple light.In fact,red,orange,yellow,green,blue,indigo,purple light mixed turn achromatic.After raining,there is a lot of drip-drop in the air.When sun come out,the sunshine is refraction by the drip-drop,so appear the Rainbow.

Answer 4

It was a 1980's TV show for kids featuring Geoffrey, Bungle, Zippy and George; with the elementary music provided by Rod, Jane & Freddie.

Answer 5

you see... Light emits in different wavelegnths. That's why we see things have color. That color reaches our eyes first. But when light passes through a prisim or a series of water droplets, all the wavelegnths are released. there are also Moonbows. Basicly rainbows at night that are black.

Answer 6

A series (or spectrum) of 7 distinct colours that is formed when white light passes through a prism.

Answer 7

It's a spectrum of light in the sky caused by refraction of the sun's rays by rain.

Answer 8

it is the combination of lights of different coloursreaching the human eyeafter coming from the suspended rain drops after the white light from the sun suffered refraction into rain drops, one or two internal reflexions inside rain drops and refraction out of rain drops
