Okay, so I used the relationship E=cB to find that the electric field acts in the (1,-1,0) direction and hence that the wave does indeed propagate in the (0,0,1) direction. I then used U=ε0E2 to find that the energy density is U=2c2B02ε0 I'm still confused about the polariser, did you mean...

Hi, I've not posted on here before but I'm trying to keep on top of work over the summer and I'm having some real problems with this question Homework Statement Consider the plane polarised EM wave in a source free vacuum with magnetic field B = (1,1,0)B0cos(kz-wt) where B0 = 0.001T. Find...
