Thus, at twice the original distance, the intensity (power per square meter) of the light passing through a single square will be 1/4 of the original intensity. Going out still farther, tripling the original distance (3r), and the light from the original square now covers an area of 9 (= 3 2) squares. Thus, at three times the … See more As you move away from a light source, the light gets dimmer.
