Wave Speed (v) = Frequency (f) x Wavelength (λ)

Where:

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

* f is the frequency, measured in Hertz (Hz), which represents the number of wave cycles passing a point per second.

* λ is the wavelength, measured in meters (m), which is the distance between two consecutive crests or troughs of a wave.

This equation applies to all types of waves, including sound waves, light waves, and water waves.
