Question

Time taken to complete one vibration is the _________.

Answer 1

1. Time period is the time taken to complete one vibration.
2. If T is the time period of any wave, then the number of vibrations in one second will be $\frac{1}{\mathrm{T}}$ which is equal to frequency.
3. So $\mathrm{f}=\frac{1}{\mathrm{T}}\mathrm{or}\mathrm{T}=\frac{1}{\mathrm{f}}$.
4. Thus, frequency and time period are reciprocal to each other.
5. Therefore, the time taken to complete one vibration is the time period.
