# Wave Speed

Speed is defined as distance over time.

When it comes to waves, the distance is wavelength and the time is period.

Hence, wave speed = wavelegth / period

Since period is the inverse of frequency, the wave speed formula can be written as follows:

wave speed = frequency × wavelegth ⇒ *v = f × λ *

This formula holds for all kinds of waves including water waves, sound waves, light waves, etc.
