Question
Pressure variations are observed among the particles of a medium when a ______ wave propagates through it.
- Longitudinal
- Transverse
- Both a and b
- None of the above
Hint:
Pressure variations are observed among the particles of a medium when a longitudinal wave propagates through it.
The correct answer is: Longitudinal
- Longitudinal waves are waves in which the vibration of the medium is parallel to the direction of the wave propagation.
- The longitudinal waves are called pressure waves.
- Because the propagation of longitudinal waves through a medium involves changes in pressure.
- When compression and rarefaction are formed.
- So, the correct option is a.
