Question

Quizplus · Accepted Answer

A sound wave in a gas is an example of a longitudinal wave, where the particles in the medium vibrate parallel to the direction of wave propagation. Waves on a string under tension are transverse waves, where particles in the medium vibrate perpendicular to the direction of wave propagation. Light waves are also transverse waves. Therefore, options B and C are not longitudinal waves.
