| inverse | 1. Opposite in order, relation, or effect; reversed; inverted; reciprocal; opposed to direct. 2. <botany> Inverted; having a position or mode of attachment the reverse of that which is usual. 3. <mathematics> Opposite in nature and effect; said with reference to any two operations, which, when both are performed in succession upon any quantity, reproduce that quantity; as, multiplication is the inverse operation to division. The symbol of an inverse operation is the symbol of the direct operation with -1 as an index. Thus sin -1 x means the arc whose sine is x. <geometry> Inverse figures, two points lying on a line drawn from the center of a fixed circle or sphere, and so related that the product of their distances from the center of the circle or sphere is equal to the square of the radius. <mathematics> Inverse, or Reciprocal, ratio, the ratio of the reciprocals of two quantities. Inverse, or Reciprocal, proportion, an equality between a direct ratio and a reciprocal ratio; thus, 4: 2:: 1/3: 1/6, or 4: 2:: 3: 6, inversely. Origin: L. Inversus, p. P. Of invertere: cf. F.

| 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.
