Calculation Wave Speed Formula

You can calculate the speed of a wave by using the formula below.

𝑣=𝑓λ

In other words, wave speed or velocity (𝑣) is equal to frequency (𝑓) multiplied by wavelength (λ).

The unit for wave speed velocity (𝑣) is meters/second (m/s), the unit for frequency (𝑓) is hertz (hz) and the unit for wavelength (λ) is meters (m).
