Question

which of the following describes a sound wave? a. longitudinal wave that does not require a medium b. longitudinal wave that requires a medium c. transverse wave that requires a medium d. transverse wave that does not require a medium

Explanation:

Sound waves are longitudinal waves as the particles of the medium vibrate parallel to the direction of wave propagation. Also, sound waves need a medium (like air, water, or solids) to travel through as they rely on the interaction of particles in the medium.

Answer:

B. Longitudinal wave that requires a medium
