Detailed Solution

1 Hertz is equal to 60 vibration per hour.
Here, the frequency is the number of oscillations per unit of time measured in hertz (Hz). So, one hertz implies that an event occurs once every second. That means 1 hertz =1vibration per second. So we know that in 1 min = 60 sec. Therefore, 1 Hertz = 60 vibrations per minute.
