Question

"describe how this apparatus could be used to verify the inverse square law for a point source of light"

Marilyn Bob-Manuel 3ekt · Accepted Answer

obtain values of irradiance for different distances
plot a graph of I against 1/d^2
graph should be a straight line through the origin if the light is a point source
