v = fλ

Where:

* v is the wave speed (usually measured in meters per second, m/s)

* f is the frequency of the wave (usually measured in Hertz, Hz)

* λ is the wavelength of the wave (usually measured in meters, m)

What this means:

This formula tells us that the speed of a wave is directly proportional to both its frequency and wavelength. This means that:

* Higher frequency waves travel faster.

* Longer wavelength waves travel faster.

Example:

Let's say a wave has a frequency of 10 Hz and a wavelength of 2 meters. To find the wave speed, we would use the formula:

v = fλ = (10 Hz) * (2 m) = 20 m/s

Therefore, the wave speed is 20 meters per second.
