9702/22/F/M/21: (a) State the principle of superposition. #9702m21p22 #ASsuperpositionP2

(b) A transmitter produces microwaves that travel in air towards a metal plate, as shown in Fig. 4.1. The microwaves have a wavelength of 0.040 m. A stationary wave is formed between the transmitter and the plate.
(i) Explain the function of the metal plate.
(ii) Calculate the frequency, in GHz, of the microwaves.

(iii) A microwave receiver is initially placed at position X where it detects an intensity minimum. The receiver is then slowly moved away from X directly towards the plate.
1. Determine the shortest distance from X of the receiver when it detects another intensity minimum.
2. Determine the number of intensity maxima that are detected by the receiver as it moves from X to a position that is 9.1 cm away from X.
