An Infinite, Ideal Plane Wave Traveling Inside A Large Slab Of Linear Dielectric (Non-Conducting, Non- Magnetic, With Real Index Of Refraction Ni >1) Exits The Slab (At Angle 01) And Ends Up In Vacuum (N2=1). In Class And In Homework We Derived The Following Fresnel Equations: CASE I CASE II: E Field Polarized In The Plane Of Incidence E Field Polarized

 

2.) An infinite, ideal plane wave traveling inside a large slab of linear dielectric (non-conducting, non- magnetic, with real index of refraction n >1) exits the slab (at angle 01) and ends up in vacuum (n=1). In class and in homework we derived the following Fresnel equations: CASE I CASE II: E field polarized in the plane of incidence E field polarized perpendicular to the plane of incidence a+ E= 2 (1-a E 2 Cose Where = 1. B="2. In the figure, I show the direction of E, and k for some incident wave. cose, M You may assume 0, is small (it's less than the "critical angle") i) (2 pts) WHICH CASE ABOVE are we in? (Circle one) Case I, Case II could be either, neither/something else n>1 (slab) (vacuum) 8 K OE, (out of page) ii) (4 pts) Given that ni>n2=1, how does a compare with 1? (circle one!) a 1, a 1, a can be anything from 0 to , none of these, there is simply not enough information given to decide among these options. Very briefly, explain: iii) (4 pts) Given that n>n2=1, in which case above can we get ZERO reflection for some nontrivial incident angle 0 < < 90? (circle one!) Case I, Case II, both, or neither Very briefly, explain:
