Document Summary
Our eyes are sensitive to a very small part of the whole electromagnetic spectrum. Light is made up of photons; particles that transmit light. The color we end up seeing is dependent on the frequency of light. 2 characteristics of light waves are: wavelength: distance from crest of one wave to crest of next (color/hue, amplitude: the height of each wave; intensity depends on amplitude (brightness) Light that is visible to humans has wavelengths that range from 400 to 700 nanometers. The wavelength of light is related to the psychological property of color (or hue: 400 nm appears to us as violet, 700 nm appears to us as red. Intensity corresponds to the psychological property of brightness. Cornea: the transparent covering of the eye primarily responsible for bringing light into eye also acts as a lens to focus light only one focus is possible.
