Question
In a longitudinal wave, the particles of the medium vibrate ____ to the direction of wave propagation.
- Parallel
- Perpendicular
- At 30 degrees
- At 80 degrees
Hint:
The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is called transverse wave.
The correct answer is: Parallel
- In longitudinal waves, the particle of the medium vibrates parallel to the direction of propagation of the wave.
- So, the correct option is a.
