| three primary colors of light that mix to make white light | red, blue, and green |
| three primary colors of pigment that mix to make black | cyan, magenta, yellow |
| to see color, light must be | reflected |
| in a rainbow, white light becomes a rainbow because it is | refracted |
| in a filter or a window, light is | transmitted, absorbed, and reflected |
| this focuses light on the retina | lens |
| this is the clear layer of the eye that protects the inner layers (Don't get scratched there; it hurts!) | cornea |
| this brings nerve impulses to the brain | optic nerve |
| this is a hole in the eye | pupil |
| this is light sensitive tissue in the eye | retina |
| this muscle controls the amount of light entering the eye | iris |
| these cells determine color that you see. They work best in bright light | cones |
| These cells help with night vision and periferal vision; respond to amount of white light | rods |
| molecule which absorbs certain wavelengths of light and reflects others back | pigment |
| when you mix light colors you add light so the resulting light becomes | lighter |
| when you mix pigment colors, you are subtracting light because more wavelengths get absorbed, so colors get | darker |
