Chapter 5: Q21E (page 1181)
Consider two antennas separated by 9.00m that radiate in phase at 120MHz, as described in Exercise . A receiver placed 150m from both antennas measures an intensity .The receiver is moved so that it is closer to one antenna than to the other. (a) What is the phase differencebetween the two radio waves produced by this path difference? (b) In terms of , what is the intensity measured by the receiver at its new position?
Short Answer
- The phase difference between the two radio waves produced by this path difference is 4.52rad .
- The intensity measured by the receiver at its new position is 0.404.
