Document Summary

Identify which physical characteristics of light correspond to which psychological characteristics. Two physical characteristics of light waves are: Wavelength: distance from crest of one wave to crest of next. Amplitude or intensity: amplitude is the height of each wave. Describe the visual system from eye to cortex. Cornea: transparent covering of eye, brings light into eye and acts as lens. Iris: controls how much light enters the eye by changing diameter of pupil. Lens: muscles change curve of lens to see distance (manipulate focusing ability) Retina: where all the light-detecting cells exist: rods and cones (deepest layer from the surface of the eye): convert light energy into electrical energy, interneurons (transmit information from rods and cones to the ganglion cells, ganglion cells. Optic nerve: carries the neural signal produced by the retina directly to the occipital lobe, where the primary visual cortex lies. Differentiate between rods and cones (function, location, convergence)
