Inverse square law

A simple mathematical law thatís usually complicated by its description. The law states that light projected onto a surface is inversely proportional to the square of its distance from the source! See what I mean? Basically if you shine a light on a subject and then move it to twice the distance the subject will receive a quarter of the intensity. Similarly when you half the distance the intensity is multiplied by four.
