AQA AS LEVEL PHYSICS Paper 2 2021. A student investigates stationary waves using microwaves. Figure 1 shows a metre ruler fixed to a bench. The student places a microwave transmitter T at one end of the ruler and a vertical metal reflector R at the other end. R is at a right angle to the ruler. Figure 1 The student places a microwave detector D approximately one-third of the distance from T to R. When T is switched off, the microammeter connected to D reads zero. When T is switched on, ...
