Unit 4 again
still in the plan..
Amount of energy in light waves-determined by a wave’s amplitude, or height
Adjustable opening in the center of the eye through which light enters
Right of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening
Transparent structure behind the pupil that changes shape to help focus images on the retina
Multilayered tissue on the eyeball’s sensitive inner surface
Process by which the eye’s lens changes shape to focus near or far objects on the retina
Rods \ Cones?
Retinal receptor cells, rods: see gray, black, white, and twilight vision (peripheral) when codes don’t respond, cones: detect fine detail and give rise to color
Nerve that carries neural impulses from the eye to the brain
Point at which the optic nerve leaves the eye, creating a “blind” spot because no receptor cells are located there
Central focal point in the retina, around which the eye’s cones cluster
Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement
Doing many things at once
Young-Helmholtz dichromatic (three color) Theory?
Theory that the retina contains 3 different color receptors
Opponent process theory?
Theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision
