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.)
