Which phenomenon is common in both light and sound waves ?

A point source emits sound equally in all directions in a non-absorbing medium. Two point P and Q are at distances of 2 m and 3 m respectively from the source. The ratio of the intensities of the waves at P and Q is

The intensity of sound from a radio at a distance of $2$ meters from its speaker is $1 \times 10^{-2} \mu W/m^2$. The intensity at a distance of $10$ meters would be

Longitudinal waves cannot show the phenomenon of
