This is the currently selected item. The Wave speed formula which involves wavelength and frequency is given by. This equation can be used to calculate wave speed when wavelength and frequency are known.
V is the wave speed in metres per second ms.
Sound in air 340 ms. V is the wave speed in metres per second ms. What is the speed of an electromagnetic wave whose length is 35m and has a frequency of 100000000 Hz. The speed of a wave is related to its frequency and wavelength according to this equation.
