Q.
The displacement-time graph for two sound waves A and B are shown in the figure, then the ratio of their intensities $I_A / I_B$ is equal to
Waves
Solution:
$I \propto a^{2} n^{2}$
$\frac{ I _{ A }}{ I _{ B }}=\frac{ a _{1}^{2} n _{1}^{2}}{ a _{2}^{2} n _{2}^{2}}$
$=\left(\frac{2}{1}\right)^{2} \times\left(\frac{1}{2}\right)^{2}=1: 1$
