# A periodic wave has a period of 0.36 s. What is the wave frequency?

## Question:

A periodic wave has a period of 0.36 s. What is the wave frequency?

## The Periodic Wave:

In physics, a periodic wave is a wave that repeating a continuous pattern, which helps to determines its wavelength and frequency. In a periodic wave, the period is the time taken for one complete wave cycle, and the wave frequency is defined as the number of waves per unit of time. The wave frequency and the period are inversely related to each other. The S.I. unit of frequency is Hertz (Hz), or per second.

{eq}T = \dfrac{1}{f},\;{\rm{or}}\;f = \dfrac{1}{T} {/eq}
