I.ncrease the wavelength of the light
The light is broken into its seven colors (colors of the rainbow) and exits the prism at a different angle with the separated colors. It functions in the exact same way water droplets separate light to create an actual rainbow, but with cut glass instead of water.
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
White light separates into seven colours
A rainbow
As the light passes through the prism, the resulting effect is called a 'refraction'. In other words, the light enters from one side of the prism and is then 'redirected' at a right angle as it exits the prism.

What happens when light enters a prism is the light is broken up into all its natural colors. Hence what happens when you see a rainbow, all the little rain drops act as a prism.
The light sctters into a spectrum.

White light separates into seven colours
when normal white light is passed through a prism, it is split up into all the rainbow colors.
It shows color.
The top of the periscope has a prism that reflects the light to the observers prism. The object the top prism is pointed at is seen at the bottom one.
