Question

a child is standing 600m away from 40Hz sound source What is time
interval in which successive compression from the source reach him?

Bakul Biswas · Accepted Answer

Dear Student,
The time interval between successive compressions is equal to the
time period of the wave And this time period is the reciprocal of
the frequency of the wave
It is given by:
T = 1 / Frequency
= 1 / 40
= 0 025 s
