A radio station (92 .3 MHz on the FM dial) has two transmission towers d = 37 .0 m away from each other, producing signals that are completely in phase. An avid fan of this station is listening to it on her portable radio while jogging directly toward one of the towers from an initially large distance away, as shown below. Let x be her distance from the closest tower. (a) At what distance x will the jogger first experience no radio signal, due to destructive interference? (b) The jogger stops when she gets to the bottom tower. During her jog, how many times total did she experience a loss of signal?

Unformatted text preview: (A whole number is required here.) A person driving at 17 m/s crosses the line connecting two radio transmitters at right angles, as shown in the figure below. The transmitters emit identical signals in phase with each other, which the driver receives on the car radio. When the car is at point A, the radio picks up a maximum net signal. (a) What is the longest possible wavelength of the radio waves? (b) How long after the car passes point A does the radio experience a minimum in the net signal? Assume that the wavelength has the same value as in part (a)....
