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

Answer

The number of oscillations produced in one second is called frequency.

Frequency of the sound = 100 Hz

 

Hence, 

Number of oscillations in 1 second = 100

Number of oscillations in 60 seconds = 60 × 100                        

                                                                  = 6000

 

Number of vibrations in 1 minute is 6000.
