Document Summary

Light is a form of electromagnetic radiation- energy produced by vibrations of electrically charged material. We"re going to treat light as made up of waves when moving around in the world, and being made up of photons when absorbed. If the light isn"t reflected or absorbed, it"s transmitted through the surface. the course of a wave of energy that passes into something from another medium. Our eye structure, in order that the light goes through: cornea: the transparent tissue that provides a window to the world. It has a rich supply of transparent sensory nerve endings. Refraction happens here: the aqueous humor: the watery fluid in the anterior chamber in the eye. Supplies oxygen and nutrients to, and removes waste from, both corne and the lens. Second refraction occurs here: pupil: the dark, circular opening at the centre of the iris in the eye, where the light enters the eye.
