If all colors are passed through another prism white light will emerge
This may sound funny, but check out the pink Floyd album dark side of the moon, look at the front then look at the back it is an upside down image with colors going in and light going out. Imagine those are the colors from the front. (The triangle is a 2D interpretation of a triangular prism)
The main function of prism is to exploit the sun's white light into its constituents seven colors.Because these seven colors(VIBGYOR) have different wavelengths & hence different refractive index means different angle of refraction.
But if we place another prism inverted with 1st one then it reverse the action of first, it converges all colors to form a single white light.
There are more than seven but only seven are visible. They are red, orange, yellow, green, blue, indigo, violet, and the one that cant be seen is ultra-violet.
It is called Visible light Spectrum.
An optical prism can be used to disperse light from the sun's spectrum into all of its constituent colors. It is the same concept that gives rise to the phenomenon of rainbows.
Prisms create spectrum of colors by the cause of refraction.
"Color" is a way of describing how an object interacts with electromagnetic radiation in the visible region of the spectrum. This has no impact whatsoever on how it interacts with electromagnetic radiation in the microwave region of the spectrum. So, no, they don't.
Yes visible light is part of what is called the electromagnetic spectrum. White light is actually all of the visible spectrum being seen. This is demonstrated by white light passing through a prism and being broken up into its component colors, such as a rainbow.
It is the spectrum of visible light, which has the colors of the rainbow.
If you pass white light through a prism, it will separate out into the individual colors of the visible spectrum.

The colors you see in a rainbow Continuous spectrum :)
When light goes through a prism, it separates into a rainbow.
visible spectrum
White light contains all of the colors in the visible spectrum. Black contains none of these colors.

yes, there are more colors tha the visible spectrum!
