1. The problem statement, all variables and given/known data I ave a research to do on Faraday effect. I found an explanation were they said that a linearly-polarized beam of light may be considered as the superposition of equal amounts of right- and left-circularly polarized beams. The right- and left-circularly polarized beams or pi/2 and -pi/2 right? If I'm right they are at 180 degree of each other and it give 0 as along the axes not a linear polarized wave. I used Matlab: t = 0:pi/50:4*pi; X1 = cos(t-pi/2) Y1 = sin(t-pi/2) X2 = cos(t+pi/2) Y2 = sin(t+pi/2) X3 = X1+X2 Y3 = Y1+Y2 plot3(t,X1,Y1,t,X2,Y2,t,X3,Y3) grid on axis square 2. Relevant equations Is it the explanation or my interpretation and if its me what is the correct way???
