Question

In a gaseous medium, a sound wave is ___.

• A. longitudinal
• B. transverse
• C. non-mechanical
• D. (a) and (b) above.

Answer 1

The correct option is A longitudinal

In a sound wave in gaseous medium, particles vibrate about their mean position along the direction of the wave. Hence, sound wave is longitudinal in nature.
In gaseous medium, transerve waves are not possible because of the properties of gases.
