1. Shown below are pictorial and mathematical representations of an electromagnetic plane wave propagating through empty space. The electric field is parallel to the z-axis. The magnetic field is parallel to the y-axis. (x, y, z, t) = E, sin(kx + wt) 2 E B(x, y, z, t) = B. sin(kx + wt) a. The points P, Q, R, and S in the diagram above lie in the x-y plane. i. For the instant shown, rank points P, Q, R, and S according to the magnitude of the magnetic field at these 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 field at these points, from largest to smallest. If the electric field 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. X 1.
