What is the formula for calculating the time period of a wave?

The time period of a wave, which is the duration of one complete cycle of the wave, is calculated using the formula that relates it to frequency. The frequency of a wave is defined as the number of cycles that pass a point in one second, measured in hertz (Hz).

To find the time period (T), which is the inverse of frequency (f), the formula is given as T = 1/f. This indicates that as the frequency increases, the time period decreases, and vice versa.

In this understanding, if the frequency is, for example, 2 Hz, the time period would be T = 1/2 = 0.5 seconds. This shows how many seconds it takes for a single wave cycle to complete.

Other options may confuse terms related to wave motion but do not accurately define the simple relationship between time period and frequency as stated in this correct answer. Thus, option C directly and accurately describes how to calculate the time period of a wave.
