Question
The pressure of a medium _____ when a longitudinal wave propagates through it.
- Becomes uniform
- Stays the same
- Becomes non-uniform
- Dilutes
Hint:
The longitudinal waves are called pressure waves. Propagation of longitudinal waves through a medium involves changes in pressure and volume of air when compression and rarefaction are formed.
The correct answer is: Becomes non-uniform
- The particles in a medium move back and forth in longitudinal waves.
- It creates a pattern of compressions (high-pressure regions) and rarefactions (low-pressure regions).
- Therefore the pressure of a medium becomes non-uniform.
- So, the correct option is c.
