Intensity-  the amount of energy in a light or sound wave, which we perceive as  brightness or loudness, as determined by the wave’s amplitude. The Eye: ganglion axons forming the optic nerve run to the thalamus, where they  synapse with neurons that run to the visual cortex. Pupil-  the adjustable opening in the center of the eye through which light  enters. Iris-  a ring of muscle tissue that forms the colored portion of the eye around  the pupil and controls the size of the pupil opening.
