Finding frequency from wavelength and speed
WebThe speed of a wave is related to its frequency and wavelength, according to the equation: \ [wave~speed~ (v) = frequency (f) \times wavelength (\lambda)\] \ [v = f~ \lambda\] … WebSpeed = Wavelength • Frequency. The above equation is known as the wave equation. It states the mathematical relationship between the speed ( v) of a wave and its …
