The inverse square law states that intensity is inversely propor= tional to the square of the distance from the source. Symbolically:
intensit= y =3D 1 / (distance^2)

Doing a little math, when the distance is 1, the = intensity is 1. When the distance is 2, the intensity is 0.25. When the dis= tance is 3, the intensity is 0.111. When the distance is 4, the intensity i= s 0.0625.

I think this was more of an experiment to see if I c= ould do it myself and understand the math a bit better.=C2=A0
