PhysicsEasysingle choice

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

Options:

Answer:

Solution:

The intensity can be given by

$I = 2 π^{2} ρ^{2} A^{2} v$

Hence,

$\frac{I_{A}}{I_{B}} = \frac{f_{A}^{2} A_{A}^{2}}{f_{B}^{2} A_{B}^{2}}$

$\frac{I_{A}}{I_{B}} = {(\frac{1}{2})}^{2} {(\frac{2}{1})}^{2}$

$\frac{I_{A}}{I_{B}} = 1$
