Question

An electromagnetic wave is coming from the air and falling on theinterface with water.
a. consider first the case of the normal incidence an dfindthe coefficient of reflection and the coefficient oftransmission
b. let not the incidence be oblique. find the Brewsterangle. at what angle of incidence with the intensity of thereflected wave be equal to the intensity of the transmittedwave?
c. if the wave is falling obliquely from water to air, whatis the maximum angle of incidence above which T=0>

Explanation / Answer

b) =tan p =>1.33=tanp => p =53.060 critical angle for which T=0> is C sinC=1/=1/1.33=0.75 so C=48.590 critical angle for which T=0> is C sinC=1/=1/1.33=0.75 so C=48.590
