The microwaves in a certain microwave oven have a wavelength of 12.2 cm.
Required:
a. 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?
b. What is the frequency of these microwaves?
c. Suppose a manufacturing error occurred and the oven was made 6.0cm 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?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
