short-wave radio antennas aa and bb are connected to the same transmitter and emit coherent waves in phase and with the same frequency ff. you must determine the value of ff and the placement of the antennas that produce a maximum intensity through constructive interference at a receiving antenna that is located at point pp, which is at the corner of your garage. first you place antenna aa at point 258.0 mm due east of pp. next you place antenna bb on the line that connects aa and pp, a distance xx due east of pp where x
