A boy heard a sound of frequency 100 Hz at a distance of 500 m from the source of the sound. What is the time period of oscillating particles of the medium ?

Text Solution

Verified by Experts

Here, y=100 Hz: T-? The time period of oscillating particles is equal to the time period of the wave.
Time period `T = (1)/(v) =(1)/(100)=0.01s`
. The time period is 0.01s (or `1xx10^(-2)s`)
