shine off the surface and reflect back
If white light is shined through a prism, it will be dispersed into colors.
White light contains all colors of the spectrum. If white light is shined on a prism, we'd expect to see a "rainbow" emerging, and that means red, orange, yellow, green, blue and violet.
A rainbow
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
It changes its direction, then comes out the other side of the prism, and makes a small spot on the first thing it runs into. A true laser beam consists of only one wavelength (frequency) of light. So there aren't different 'colors' to get split up in the prism. One beam goes in, and one beam comes out ... aimed in a slightly different direction.
it makes a rainbow!!!!!!!!!!!!!!!! :D
Black light
If white light is shined through a prism, it will be dispersed into colors.
The laser beam is a highly monochromatic source of light. It consists of only one wavelength and hence does not get dispersed by using a glass prism.
White light contains all colors of the spectrum. If white light is shined on a prism, we'd expect to see a "rainbow" emerging, and that means red, orange, yellow, green, blue and violet.

A rainbow
when normal white light is passed through a prism, it is split up into all the rainbow colors.
Because laser light consists of only one frequency (color), so there's nothing to spread out.
Colours shine out!
There is no 'wrong angle' - it either passes through the prism or it doesn't. The blue or violet waves will be the most diffracted.
