# Inverse Square Law Calculator

The Inverse square law states that the intensity of radiation passing through any unit area is inversely proportional to the square of the distance from the point source.Examples of light intensity are illumination or gravitational force changes. The inverse square law calculator which calculates the intensity of light or radiation.
Calculate light intensity by just entering the distance between the point of origination and the point of measurement in the below calculator.

## Calculate Light Intensity

The Inverse square law states that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. Use this Inverse square law calculator to find the intensity of light/radiation from the source point.
