inverse square law

When the strength or intensity of some quantity depends inversely on the square of the distance from the source or origin of that quantity, it is said to obey an inverse square law. For example, the strength of gravitational attraction of a body is inversely proportional to the square of the distance from that body; the intensity of a sound is inversely proportional to the distance from the source of the sound.

Light and electrostatic force (Coulomb's law), are among the other phenomena that obey the inverse square law.
