* Understanding Frequency and Period:

* Frequency (f): The number of complete vibrations or cycles per second. Measured in Hertz (Hz).

* Period (T): The time it takes for one complete vibration or cycle. Measured in seconds (s).

* The Relationship: Frequency and period are inversely proportional:

* `f = 1/T` or `T = 1/f`

Calculation:

1. Given: Frequency (f) = 50 Hz

2. Formula: `T = 1/f`

3. Substitute: `T = 1 / 50 Hz`

4. Calculate: `T = 0.02 seconds`

Answer: 50 Hertz corresponds to a period of vibration of 0.02 seconds.
