Question

Consider the following statements.
$1$. In sound waves, the vibrations are perpendicular to the direction in which the wave travels.
$2$. Sound waves are elastic waves.
Which of the statement(s) given is/are correct?

• A. Only $2$
• B. Only $1$
• C. Both $1$ and $2$
• D. Neither $1$ nor $2$

Answer 1

The correct option is A Only $2$

Sound wave travel due to elastic property of material, and vibrations are in the same direction as that of wave propagation, as it is longitudinal.

So only 2nd statement is correct.
