PHOTORECEPTORS: Cells in the retina that are sensetive to light
SNELLS LAW: Formula used to describe the relationship between the angles of incident and refraction
TOTAL INTERNAL REFLECTION: When light reflect completely off the inside wall of a denser medium rather than refracting
PHOSPHOR: A substance that glows after being exposed to energized particles
CORNEA: Transparent layer of tissue on the outer surface of your eye
CONVERGING LENS: Diverging lens
MAGNIFICATION: Measure of how bigger or smaller an image is compared to an object
