Sound waves are classified as which type of mechanical wave?
ATransverse waves
BLongitudinal waves
CElectromagnetic waves
DStationary waves
Answer & Solution
Correct answer: B. Longitudinal waves
1. In a sound wave the medium particles vibrate along the direction the wave travels.
2. This back-and-forth motion in the same direction defines a longitudinal wave.
3. Transverse waves vibrate perpendicular to travel, which sound does not.
