## Wave Period Formula

The following is the wave period formula:

T = 1/ f

- Where T is the wave period (seconds)
- f is the frequency (hz)

The wave period can also be calculated using the wavelength and velocity using the formula:

T = WL / V

- Where WL is the wavelength
- V is the wave speed.

## Wave Period Definition

A wave period is defined as the total time it takes for a wave to propagate one cycle or one wavelength. A wave period should not be confused with a wavelength or a frequency. A wavelength is the distance of one propagation and a frequency is the inverse of the period.

## How to calculate a wave period?

- First, determine the information available to you. You should be provided either the frequency or both the wavelength and the wave speed.
- Next, determine the formula you should use. For this example we will say that frequency was provided and it is equal to 50hz.
- Finally, calculate the wave period using the formula above. Using the formula we find the wave period to be 1/50z = .020 seconds.

## FAQ

**Is wave period the same as wavelength?**

Wave period and wavelength are related, but not the same. The wave period can be calculated using the wavelength and the wave speed.

**How are wave period and frequency related?**

Wave periods and frequencies are the inverse of each other. To convert between the two you must divide one by the value.

**Is a wave periodic motion?**

Waves are typically considered periodic motion when analyzing waves of things like photons and radio waves. Waves of water are not.

**What causes a wave period to change?**

Looking at the equation above for calculating the wave period, it can be seen that a wave period would change with a change in wavelength or wave speed. For example, light waves would change in wave speed when moving through different medium.
