Question
The number of vibrations or oscillations per second is called:
- Frequency
- Time period
- Amplitude
- None
Hint:
If the body vibrates 10 times in 1 second, the frequency of the body is 10 Hz.
The correct answer is: Frequency
Frequency. Frequency is defined as the number of oscillations/vibrations completed in 1 unit of time. If the body vibrates 10 times in 1 second, the frequency of the body is 10 Hz.
