The frequency of a source of sound is `100 Hz`. How many times does it vibrate in a minute ?

Text Solution

Verified by Experts

Since the frequency of the source of sound is `100 Hz`,
number of vibrations of the source in `1 second = 100`
Number of vibrations of the source in 1 minute (i.e., 60 second) `= 100 xx 60 = 6000 Hz`.
