Unformatted text preview: HW 8 Phys5406 S10 due 4/8/10 1) A monochrmatic plane, unpolarized electromagnetic wave of angular freqency is mov ing as in the diagram on page 277 of my notes. Calculate the fraction of the intensity transmitted from the Poynting vectors and show that this equals 1R, where R is the frac tion of the intensity reflected. 2) The situation is that of problem 1, except the incident and transmitted media are non magnetic. Consider two cases: a) n = 1 , n = 1 . 5 and b) n = 1 . 5 , n = 1. For each case graph as a function of incident angle, (0 , / 2), the following: i) the transmitted angle, , ii) the reflection coefficients, R bardbl , R , iii) the transmission coefficients, T bardbl , T , iv) the fraction of the intensity transmitted, v) pick out B and if any c from the graphs, vi) in terms of R bardbl , R , what would these quantities be if the wave was traveling from the transmission to incident region with reversed wave vector, vii) in case b where the incident angle is larger than the critical angle, cos...
