An electromagnetic wave of intensity is propagated in the air and normally falls upon the surface of a medium of refractive index n. Knowing that the transmitted intensity is 80% of that incident, determine the value of n. Also determine the amplitudes of the electric fields of the incident, reflected and transmitted waves. (Io = 50 W / m2.)
