1. The problem statement, all variables and given/known data plot the magnitude |r| of the reflection coefficient as a function of incident angle from 0 to 90 degrees with a step size of 1 degree for the following cases: (ill only post one) A transverse electric plane wave in incident from air to glass 2. Relevant equations r = (n1cosθi - n2cosθt)/ (n1cosθi + n2cosθt) 3. The attempt at a solution I was just going to plot r vs degrees but i only know the incident angles, 0 though 90. What i do about the other angle? I'm currently trying to plot it in excel. I think he expects us to plot it in matlab but i have no experience with matlab.
