To better understand the polarization consider two components ofthe electric field:
Ex(t) = 3 Cos (w t) and Ey(t) = 4 Cos (w t-phi). Then determine thefunctional form of
Ey(Ex) (that is find Ey as a function of Ex at any time t) for thefollowing phase
angles ï¦ = 0, 45, 90, -90, 180 degrees. State these functionalforms (polarizations)
and sketch them in (Ex, Ey) plane being as specific as you can withmaxima and
minima on the graphs.
