Question

The frequency of a source of sound is 250 Hz . How many times does it vibrate in a minute?

Answer 1

It vibrates 15000 times in 1 minute

Answer 2

☆$\red {HELLO\:DEAR}$☆

Frequency is defined as the number of oscillations per second. It is given by the relation:

Frequency = Number of Oscillations / Total Time

Number of oscillations = Frequency × Total time

Given, Frequency of sound = 250 Hz

Total time = 1 min = 60 s

Number of oscillations/Vibrations = 250 × 60 = 1500

Hence, the source vibrates 1500 times in a minute, producing a frequency of 250 Hz.
