An em plane wave (not shown) propagates in the +z direction. A long thin wire connected to a light bulb lies in the xy plane. The light bulb glows the brightest when the wire is parallel with the +y axis. See diagram below. • Consider an instant at which the electric field at the location of the wire has its largest magnitude. Draw the direction of the electric field and the magnetic field at this instant. If more than one answer is possible, draw diagrams corresponding to each case. • If the frequency of the em wave is 1.0 × 106 Hz, how long would it take for the direction of the electric field at the location of the wire to reverse? During this time, did the em wave travel a distance less than, greater than, or equal to one wave- length? long thin wire light bulb
