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

A

1 s

B

2 s

C

0.1 s

D

0.01 s

Text Solution

Verified by Experts

The correct Answer is:
A
Time interval between a compression and adjoining rarefaction:
`=T/2 = 1/(2n) = 1/(2 xx 50) = 0.01 s`
