The stimulus: light form of electromagnetic radiation that travels as a wave moving naturally at the speed of light light waves vary in amplitude (affects perception of brightness), wavelength (perception of colour) & purity (how varied the mix is) Eye channels light to the neural tissue that receives it (retina) & they house that tissue light enters eye through cornea lens is the transparent eye structure that focuses the light rays falling on the retina. The retina: the brain"s enboy in the eye. Optic disk is a hole in the retina where the optic nerve bre exit the eye (bc its a hole you cant see the image that falls on it aka blindspot) Cones are specialized visual receptors that play a key role in daylight vision and colour vision fovea is a tiny spot in the centre of the retina that contains only cones; visual acuity is greatest at this spot.
