Question

Time period of a vibration is the reciprocal of its

• A. Frequency
• B. Wavelength
• C. Amplitude

Answer 1

The correct option is A

Frequency

1. The number of vibrations in a unit of time is called frequency.
2. The time taken to complete one vibration is called the time period of vibration.
3. $\mathrm{Time}\mathrm{period}=\frac{1}{\mathrm{Frequency}}$
4. Hence, option (a) Frequency is correct.
