Answer:
Option C
Explanation:
The frequency of a wave is defined as the number of wave cycles completed in one second.
It is denoted by f and the SI unit of frequency is Hertz(Hz) or cycles per second.
The time period of a wave is defined as the time taken by the wave to complete one vibration or one wave cycle.
It is denoted by T and its SI unit is second.
The relation between frequency and time period is given by
frequency = [tex]\frac{1}{Time period}[/tex]
