The amplitude of a lightwave determines our perception of:

In Helmholtz's trichromatic theory, which color is sensitive to short wavelengths?

The eye muscle that expands and contracts to change the size of the pupil for light:

The amount of energy in a light or sound wave; perceived as brightness or loudness

The number of complete wavelengths that pass a point in a given time:

Constructs perceptions from the sensory input by drawing on our experience and expectations:

The process of organizing and interpreting sensory information

Retinal receptors that detect black, white, and gray; needed for peripheral and twilight vision
