Question

Write down the electric field and associated magnetic field in vacuum for a traveling plane wave with the following properties. The amplitude of the electric vector is E0 and the frequency is ω. The radiation is linearly polarized in the y-z plane at an angle α of π/4 with respect to the y-axis, and it is traveling in the +x direction. The electric and magnetic field can be written in the following way

E = E0cos(ωt+(−1)bEkx)(cExˆ+dEyˆ+eEzˆ)
B = cos(ωt+(−1)bBkx)(cBxˆ+dByˆ+eBzˆ)

calculate :
dE=
eE=
dB = (Enter an expression in terms of E0, c)
eB = (Enter an expression in terms of E0, c)
