The two media are lossless dielectrics with n1>n2

  1. Jan 9, 2012 #1
    1. The problem statement, all variables and given/known data
    The two media are lossless dielectrics with n1>n2. If θ exceeds thtee critical angle,
    state how b affects the amplitude and phase of the reflected wave, and give a physical
    reason for your statement
    θ:angle between incident wave and normal line
    b:distance between

    Hello tony8. Welcome to PF !

    What have you tried?

    Where are you stuck?

    I see that you're relatively new to PF. According to the rules of this forum for Home Work Help:
    So you see, ours hands are tied until you show us something.

    I think the EM wave would totally reflect
    I am confused why b will affect the reflected wave
