The Inverse-Square Law with Data Loggers
Bates, Alan
Physics Teacher, v51 n5 p290-291 May 2013
The inverse-square law for the intensity of light received at a distance from a light source has been verified using various experimental techniques. Typical measurements involve a manual variation of the distance between a light source and a light sensor, usually by sliding the sensor or source along a bench, measuring the source-sensor distance and the received light intensity at each value of distance. In this experiment, motion and light sensors, with data-logging software, are used to simultaneously measure the light source-sensor distance and the light intensity falling on the light sensor.
