The displacement-time graphs for two sound waves $A$ and $B$ are shown in Figure 6.98, then the ratio of their intensities $I_{A} / I_{B}$ is equal to:

Options:

Answer:

Solution:

Wave $A$ has amplitude $2 a$ and wave $B$ amplitude $a$ ; $B$ has twice the frequency of $A$ . $I \propto f^{2} A^{2}$ , so $I_{A} / I_{B} = \frac{1 \times 4}{4 \times 1} = 1$ .
