1. Shown below are pictorial and mathematical representations of an electromagnetic plane wave propagating through empty space. The electric eld is parallel to the z-nxis. The magnetic eld is parallel to the yuis. ' a. The points P, Q, R. and S in the diagram above lie in the xy plane. i. For the instant shown, rank. points P. Q. R, and 3 according to the magnimde of the magnetic eld a! [hose points. from largest to smallest. If the magnetic field is zero at any of these points, state that explicitly. Explain your reasoning. ii. For the instant shown. rank points P, Q, R. and S according to the magnitude of the electric eld at these points. 'om largest to smallest. If the electric eld is zero at any of these points. state that explicitly. Explain your reasoning. b. In which direction is the electromagnetic wave propagating? Explain how you can tell.
