Document Summary
Three key properties: amplitude (a measure of brightness, wavelength (determines colour, our visible rang is 360- 750 nm, purity (a measure of saturation or richness of colour) The path that light follows from when it hits the eye is as follows: cornea, pupil. Black part of the eye, opening that controls amount of light let in. Coloured part, muscle that controls movement of pupil. Inverts and reverses image due to curvature shape, this is later corrected by the brain. Employs accommodation to help focus light: for close images, it get rounder and fatter, for far images, it gets long and skinny. Light travels through vitreous humour (jelly like substance inside the eye) before it hits the retina at the back. Very important because this is where the light is translated into a neural impulse. There are three retinal layers: photoreceptors, bipolar cells, ganglion cells.
