2 radio antennas are 100m apart along a north-south line. Theybroadcast identical radio waves at a frequency of3.0MHz. Your job is to monitor the signal strength with a handheldreceiver. To get to your 1st measuring point, you walk 800m eastfrom the midpoint berween the antennas, then walk 600 mnorth.
a. what is the phase difference between the waves at this point?
b. Is the interference at this point maximum constructice,perfect destructive, or somewehere in between? explain.
c. If you now being to walk father north, does the signalstrenth increase, decrease or stay the same?
