what is a rainbow?

Answer 1

Sunlight passing through water droplets in the sky causing the light to refract into different wavelengths. Different wave lengths of light appear as different colors to the eyes.

Answer 2

Rainbow is a bow formed by rain drops.It is actually a full circle.We see only an arc as it is limited by horizon.Rainbows form when rain drops bend (refract) light rays from the sun,acting much like prisms by splitting the light into its seven component colours.Each colour emerges again at a slightly different angle depending upon its wavelength,producing separate bands of color.Red(the longest wavelength) appears on the ouside of the rainbow followed by orange,yellow green,blue,indigo and violet .The higher the sun,the flatter is the rainbow.A double rainbow occurs when the rays are reflected twice inside the drops.

Answer 3

As sunlight enters the rain drops, part of the visible light is refracted, and colored light exit the drops, back toward our eyes (like a prism). However, these colors are seen at specific angles, between 40 and 42 degrees, with each color seen at a specific angle. Because of this, each drop produces only one color we can see. So, instead of seeing random colors everywhere, we get the distinct shape and color of a rainbow.

Along with this, because each person views the rainbow slightly differently then another person…such as with differences in height and where they are standing…different drops will produce the different colors. As a result, the rainbow you see is actually a different rainbow than someone right next to you will see. The rainbow is distinctively your own.
Note...in order to see a rainbow, you must be facing the falling rain with the sun at your back.

Also, there is such a thing as a "secondary" bow. This secondary bow can be seen as a pale "mirror" image compared to the main bow. It develops as a result of sunlight entering the raindrops at angles that allow the light to make two internal reflections in each drop. Each reflection weakens the intensity, making it faded in appearance. The colors are also in reverse, with red on the inside, and violet on the outside.

Answer 4

To me a rainbow is fain left over that comes together and it makes a rainbow. And someone told me is Gods promise to make things better.

Answer 5

As light from the sun passes through water droplets in the atmosphere, the light is split (refracted) into the individual wavelengths that make it up. Each wavelength is refracted at a slightly different angle so we see each color individually.

Answer 6

rain drops act as a prism, and what you see is refracted light through the drops.

Answer 7

The result of prismatic effect.

Answer 8

God's promise to never again destroy the earth by water.

Answer 9

refracted light?

Answer 10

Yeah, what he said
