Question
Longitudinal waves are those ___.
- In which the particles of the medium vibrate along the direction of motion of the wave.
- In which the particles of the medium vibrate perpendicular to the direction of motion of the wave.
- Which does not require a material medium for their propagation.
- None of the above
Hint:
Longitudinal wave travels through the medium using particulate motion
The correct answer is: In which the particles of the medium vibrate along the direction of motion of the wave.
These waves travel making compressions and rarefactions as they move
