Consider two antennas separated by 14.0 mthat radiate in phase at 85 MHz. Areceiver placed 150 m from both antennas measures an intensity/0. The receiver is moved so that it is2.2 m closer to one antenna than the other.
a) What is the phase difference ? between the two radio waves produced by this path difference? radb) In terms of /0, what is the intensitymeasured by the receiver at its new position? X/0
