A point source emits sound equally in all directions in a non-absorbing medium, two points \( \mathrm{P} \) and \( \mathrm{Q} \) are
\( \mathrm{P} \) at distance of \( 2 \mathrm{~m} \) and \( 3 \mathrm{~m} \) respectively from the

W. source. The ratio of the intensities of the waves at \( P \) and \( \mathrm{Q} \) is
(1) \( 9: 4 \)
(2) \( 2: 3 \)
(3) \( 3: 2 \)
(4) \( 4: 9 \)
