The speed of an electromagnetic wave in a material medium is given by v = 1/√µɛ , µ being the permeability of the medium and ɛ its permittivity. How does its frequency change?

  • 3

Frequency an electromagnetic wave depends on the sourceof wave and is independent of the nature of a medium.

    1 Answer

    1. The frequency of an electromagnetic wave does not change in a material medium, as it depends solely on the source. However, the wave’s speed and wavelength decrease due to the medium’s permeability (µ) and permittivity (ɛ).
