The speed of the electromagnetic wave in free space is therefore given in terms of the permeability and the permittivity of free space by c 1 ϵ0m0. Find the wavelength of a wave traveling at 20 ms at a frequency of 5 Hz. V is the wave speed in metres per second ms.
In a vacuum vph c0 299792458 meters per second a fundamental physical constant.
If you want to calculate the wavelength of a wave then all you have to do is plug the waves speed and waves frequency into the equation. Find the wavelength of a wave traveling at 20 ms at a frequency of 5 Hz. The speed of a wave is related to its frequency and wavelength according to this equation. Maxwell deduced that the speed of propagation of an electromagnetic wave through a vacuum is entirely determined by the constants and see Eq.
