Wave speed frequency wavelength. The amplitude phi and the cos portion of the partial derivatives would all cancel out. This equation can be used to calculate wave speed when wavelength and frequency are known.
Wave speed frequency wavelength.
A periodic wave with wavelength. The speed of a wave is related to its frequency and wavelength according to this equation. Average speed total distance total time Typical units are kilometers per hour kph miles per hour mph meters per second ms and feet per second fts. F is the frequency of the wave.
