Document Summary
380nm light = violet: 760 nm = red. All other radiant energy is invisible to our eyes. Ultraviolet radiation, x-rays, and gamma rays have shorter wavelengths than visible light has. Infrared radiation, radar, and radio waves have longer wavelengths. Visible spectrum: part of our eyes can detect; the part we see as light. Cornea: transparent tissue covering the front of the eye: admits light. Sclera: tough outer layer of the eye that coats the rest of the eye: the white of the eye. I ris: consists of 2 bands of muscles that control the amount of light admitted into the eye. The brain controls these muscles and thus regulates the size of the pupil, constricting it in bright light and dilating it in dim light. Aqueous humour: the space immediately behind the cornea; means watery fluid". Produced by tissue behind the cornea that filters the fluid from the blood.
