| inverse-square law |
A relation between physical quantities of the form: x is proportional to 1/y 2 , where y is most often a distance, and x is often a force or flux. An example of the inverse square law is the decrease of radiative flux with distance from a point source, as is often used to approximate radiation reaching the earth from the sun.

| inverse square law |
A law of physics that states that light from a point source fall off inversely to the square of the distance. As a example, if a light is 10 feet from your subject and you move it to 20 feet, you'll only have 1/4 the lighting intensity. If you move the light to 40 feet, it will now have only 1/16th the intensity.

| inverse square law |
An equation that relates the intensity of a light source to the illumination it produces at a given distance. Light diminishes over distance in accordance with the Inverse square law, which states that doubling the flash-to-subject distance reduces the light falling on the subject to one-quarter.

| inverse-square law |
The law that a field follows if its strength decreases with the square of the distance. Fields that follow the inverse square law rapidly decrease in strength as the distance increases, but never quite reach zero.
