The frequency of a source of sound is 100 Hz. How many times does it vibrate in a minute?
The no. of oscillations produced in one second is called frequency .
Frequency of sound = 100 Hz
Total time = 1 min = 60 s
We know that,
Number of oscillations = Frequency × Total time
Number of oscillations/Vibrations = 100 × 60 = 6000
Therefore , the source vibrates 6000 times in a minute, producing a frequency of 100 Hz.
