How to Calculate Inverse Square Law?
Inverse Square Law calculator uses Luminance = Intensity of Transmitted Light/Distance^2 to calculate the Luminance, The Inverse Square Law formula is defined as a law stating that the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source. Luminance is denoted by L_{v} symbol.
