What is the formula to calculate the period of a wave?

The formula to calculate the period of a wave is defined as the inverse of the frequency. The period is the time it takes for one complete cycle of the wave to pass a given point. Therefore, if you know the frequency of the wave, which is the number of cycles per second, you can find the period by taking the reciprocal of that frequency. This relationship is expressed mathematically as:

Period (T) = 1 / Frequency (f)

Thus, when the frequency increases, the period decreases, and when the frequency decreases, the period increases. This fundamental relationship is crucial in understanding wave behavior in various contexts, such as sound and electromagnetic waves.
