Question

The frequency of a source of sound is 250 Hz. Calculate the number of times, the sound vibrates in one minute. Also, calculate the time period?

Answer 1

Given frequency v = 250 Hz

Thus, the number of vibrations of the source of sound in one second = 250

Therefore no. of vibrations in one minute = 250 x 60 = 15000

The time period, T = \(\frac{1}{v}=\frac{1}{250}\)

T = 0.004 second
