Question

In a longitudinal wave, there is a state of maximum compression at a point at an instant. The frequency of the wave is 50 Hz. After what time will the same point be in the state of maximum rarefaction?

Answer 1

The internal between a compression and adjoining rarefaction

= \(\frac{T}{2}=\frac{1}{2v}=\frac{1}{2\times50}=\frac{1}{100}s\)
