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). For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/Read more
