Document Summary
Physics of light waves: greater the amplitude, more light is being relected/emited by that object (brighter, larger wavelength refers to light with lower frequency (vice-versa) o, purity. Light made of single wavelength is completely saturated. Most light we usually see is a combinaion of many wavelengths. Components of eye: light passes through curved cornea (transparent window at front of eye) which begins focusing process. Rest of eye covered by white part called sclera, a tougher membrane: focused light passes through pupil (round window, seen as black dot in middle of eye), who"s size is controlled by the iris. The lens: curvature of lens causes images to land on reina upside-down and reversed from let to right. Final image if a product of brain acivity, so we see everything properly: lens if lexible and can be altered by surrounding muscles to focus on near vs far objects.
