# Wave Speed: Relationships

WAVES-QKJQ8H

All waves can be described by the wave equation: $v=\lambda f$, where $v$ represents the velocity, $\lambda$ the wavelength, and $f$ the frequency of a wave.

According to the wave equation, if the wavelength of a wave remains constant, its velocity and frequency are

related.
If the velocity remains constant, the wavelength and frequency are

related.
If the frequency remains constant, the velocity and wavelength are

related.
