Suppose a manufacturing error occurred and the oven was made 6.0 cm longer than specified in part (a). In this case, what would have to be the frequency of the microwaves for there still to be five antinodal planes of the electric field along the width of the oven?

If the RMS magnetic field strength of a sinusoidal plane EM wave is 0.368 millitesla, what is the average pressure it would impose on a reflective surface? N/m2 is the appropriate unit of measurement.

A 4.25 m diameter university communications satellite dish receives TV signals that have a maximum electric field strength (for one channel) of 7.5 μV/m . (a)  What is the intensity of this wave in W/m2?  (b)  What is the power received by the antenna in W?  (c)  If the orbiting satellite broadcasts uniformly over an area of 1.50 × 1013 m2 (a large fraction of North America), how much power does it radiate in W?

To maximize the magnitude of the current induced in a receiving antenna, should the antenna be oriented parallel or perpendicular to the polarization of the electromagnetic wave? Explain your reasoning.
