The process of seeing green light is a photo-chemical reaction in the rods and cones of your retina.
A green light
When red light strikes a green wall you see a brown wall!
YOU SEE..... your mom
When white light is made up of many colors. The reason you see green is because the green object reflects green light back to you and and all the other colors are absorbed by the object.
The wavelength of the light affects the way that we see it.

White light is a mixture of many colors. If you see green when you look through a green glass, plastic, or whatever, it means that it lets the green light pass, other colors not.
When red light is reflected on a green surface, you would see black. This is because red light is absorbed by the green surface, rather than being reflected back to your eyes.

If light has no red or blue, you would see the color green. Green is a combination of yellow and blue wavelengths, and when there is no red or blue light present, the resulting color perceived by the eye is green.
Light that is white contains all the colours. When the light hits the leaf, it absorbs all the colours apart from the green light which is reflected back out to your eyes. So you see the leaf as green.
A green leaf absorbs most colors of light except for green; it mainly absorbs red and blue light. The green color we see is reflected light, making the leaf appear green to our eyes.
