### What is Meant by the Inverse Square Law?

In Physics, inverse square law is a statement which states that a given physical quantity is inversely proportional to the square of the distance from the source to that of the physical quantity. The magnitude of sound, light, and gravity obeys the inverse square law. The inverse square law is used to calculate the source to film distance, radiation safety, X-ray exposure, and so on.
