SATPHY-GAVKXE

The intensity of light due to a point light source is inversely proportional to the square of the distance from the source.

If the intensity of light due to a point light source is $16\ Watts/m^{2}$ at a distance of $3.0\ m$ from the source, what is the intensity at a distance of $12.0\ m$ from the source?
