Question

An electromagnetic wave is moving in the $+x$-direction (so $\vec{v} = c\hat{i}$). At some place in space and moment in time its electric field is given by $\vec{E} = (960 \text{ N/C})\hat{j}$. What is the magnetic field of the wave at this place and moment? What is the Poynting vector of the wave at this place and moment? Assume that the fields are at their maximum values at this point (meaning that $E_0 = 960 \text{ N/C}$ is the amplitude of the oscillating electric field). What is the intensity of this light? What is the energy density of this EM wave at this moment in time (when the fields are at their maximum)? What is the average energy density of this EM wave over several cycles?
