Propagation vector k
WebWhere ω = 2πf (the angular frequency) k = the wave number, the rate of change of phase with distance: The wave number k is frequently found in EM theory, it describes the variation with distance along the propagation axis whereas ω t is the variation with time. The ratio of E to H is the impedance of free space (by Ohms law): WebElectromagnetic waves are transverse waves. The wave number is k = 2π/λ, where λ is the wavelength of the wave. The frequency f of the wave is f = ω/2π, ω is the angular frequency. The speed of any periodic wave is the product of its wavelength and frequency. v = λf.
