Mobile PhysLab: Inverse-Square

The illuminance of light radiating from a point light source is inversely proportional to the square of the distance from the light source. This App served as a photometer to automatically measure the illuminance versus different values ​​of distance. The diagram of illuminance as a function of distance is auto-generated by the App accompanying with a fitting function and the regression coefficient.
