A point source emits sound equally in all directions in a non-absorbing medium. Two points $P$ and $Q$ are at distances of 2 $m$ and $3 m$ respectively from the source. The ratio of the intensities of the wave at $P$ and $Q$ is:NEET 2005

Options:

Answer:

Solution:

$d_{1} = 2 m_{1} d_{2} = 3 m Intensity \propto \frac{1}{( distance ) ^{2}} I_{1} \propto \frac{I}{2 ^{2}} and I_{2} \propto \frac{1}{3 ^{2}} ∴ \frac{I _{1}}{I _{2}} = \frac{9}{4}$
