Description: Shows the various sources of light-incandescent, sodium vapor, mercury vapor, and fluorescent--and how they measure illumination. Uses demonstrations and equations to show how luminous intensity, luminous flux, and the amount of illumination are measured. Explains the inverse square law. Employs a knowledge of geometry and trigonometry to measure illumination of tilted surfaces.
