The frequency of a source of sound is 60...

The frequency of a source of sound is 600 Hz. How many times does it vibrate in a minute?

Text Solution

Verified by Experts

The number of vibrations (complete waves or cycles) produced in one second is called frequency of the wave.
Hence, in one minute `600xx60` vibrations are produced = 36000 (Need clarification)
