WHAT DOES INVERSE SQUARE LAW MEAN IN ENGLISH?
In physics, an inverse-square law is any physical law stating that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. In equation form: The divergence of a vector field which is the resultant of radial inverse-square law fields with respect to one or more sources is everywhere proportional to the strength of the local sources, and hence zero outside sources. Newton's law of universal gravitation follows an inverse-square law, as do the effects of electric, magnetic, light, sound, and radiation phenomena.

Inverse Square Law The relationship between distance and intensity of radiation
is called the inverse square law because the intensity of radiation varies
inversely as the square of the source- film distance (SFD) (Fig. 2-10). Target

The solutions to square law problems are always the inverse of those for solving
inverse square law problems. For example, if a distance change would result in
twice as dark a film by the inverse square law, then the technique that would be ...

The Nature and Growth of Modern Mathematics
But in 1666, all of this was conjecture on Newton's part, and he wished to provide
a deductive proof that gravitational force actually obeys the inverse-square law, F
= k/d2. He was able to do so by assuming the validity of Kepler's third law.

A sphere three times as big as the first one will have nine times the area, so the
