The microwaves in a certain microwave oven have a wavelength of 12.2 cm. How wide must this oven be so that it will contain five antinodal planes of the electric field along its width in the standing wave pattern? Suppose a manufacturing error occurred and the oven was made 4.0 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?
