A person is listening to a tone of `500 Hz` sitting at a distance of `450 m` from the source of the sound. What is the time interval between successive compressions from the source ?

Text Solution

Verified by Experts

The time interval between two successive compressions is equal to the time period of the wave. This time period is reciprocal of the frequency of the wave and is given by the relation: T= 1 / Frequency = 1/ 500 = 0.002 s
