An electromagnetic wave is propagating through glass whose refractive index may be taken as n=1.5. The peak magnetic field amplitude in the wave is measured to be 4.0×10−7T.
(i) Calculate the speed of the wave in the glass.
(ii) Determine the corresponding peak electric field amplitude.
(iii) If the frequency of the wave is 5.0×1014Hz, compute its wavelength inside the glass.
