Problem
Light of frequency 6.0×1014Hz enters a non-conducting medium having relative permittivity εr=4.0 and relative permeability μr=1.0.
(i) Calculate the speed of the wave in the medium.
(ii) Determine its wavelength inside the medium.
(iii) If the electric field amplitude inside the medium is 5.0Vm−1, find the magnetic field amplitude there.
