Question

Define time period and frequency. How are they related to?

Answer 1

1. Time period is defined as the time taken to complete one vibration or oscillation.
2. SI unit of time period is second (s).
3. Frequency is defined as the number of vibrations or oscillations completed in unit time.
4. SI unit of frequency is hertz (Hz).
5. Time period is reciprocal to frequency.
6. Mathematically we can write,

$Timeperiod=\frac{1}{frequency}$.
