2019 CAIE AS & A level October November Physics Paper 13 Q. No. 26 (9702/13/O/N/19) by Sajit Chandra Shakya from Nepal Chapter - SUPERPOSITION OF WAVES In an experiment to demonstrate a stationary wave, two microwave transmitters, emitting waves of wavelength 4 cm, are set facing each other, as shown. A detector is moved along a straight line between the transmitters. It detects positions of maximum and minimum signal. The detector is a distance d from the left-hand transmitter. Assume that both transmitters are at antinodes of the stationary wave. Which row gives a value of d for a maximum and for a minimum?
