1. The problem statement, all variables and given/known data The B field of a monochromatic plane wave is B~=B0~ exp(i(kz-wt)[sqrt(3)/2 x-hat + 1/2 y-hat] Find E~ in terms of B0~. and the polarization angle. 2. Relevant equations We know E~=Eo~ exp(i(k.r-wt)nhat B~=B0~ exp(i(k.r-wt)(k-hat x n-hat) nhat = cos(theta)xhat + sin(theta)yhat 3. The attempt at a solution Would have been trivial if given E instead of B. What do I do?
