A point source emits sound equally in all directions in a nonabsorbing medium, Two points P and Q are at distance of 2m and 3m respectively from the source. The ratio of the intensities of the waves at P and Q is (a) 9 : 4 (b) 2 : 3 (c) 3 : 2 (d) 4 : 9
Added by Arun B.
Step 1
Therefore, the ratio of intensities at points P and Q can be calculated using the formula: \( \frac{I_P}{I_Q} = \left( \frac{r_Q}{r_P} \right)^2 \), where \( r_P = 2m \) and \( r_Q = 3m \). Show more…

A point source emits sound equally in all directions in a non-absorbing medium. Two points $P$ and $Q$ are at a distance of $9 \mathrm{~m}$ and $25 \mathrm{~m}$ respectively from the source. The ratio of the amplitude of waves at $P$ and $Q$ is (a) $\frac{3}{5}$ (b) $\frac{5}{3}$ (c) $\frac{9}{25}$ (d) $\frac{25}{9}$
