Sound waves cannot be polarized . Why ? Only transverse waves can be polarized .But sound waves are longitudinal. so cannot be polarized.

Question

$\begin{array}{1 1} \text{Since they are transverse waves }\\ \text{Since they are longitudinal waves } \\ \text{Since they are both transverse and longitudinal waves} \\ \text{They are of large frequency than light} \end{array}$
