Answer: The product of wavelength and wavenumber of an electromagnetic wave is equal to
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.
