Two radio antennas separated by d = 306 m, as shown in the figure below, simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x = 1,170 m from the center point between the antennas, and its radio receives the signals. Hint: Do not use the small-angle approximation in this problem. (a) If the car is at the position of the second maximum after that at point O when it has traveled a distance of y = 400 m northward, what is the wavelength of the signals? 105 X Your response differs from the correct answer by more than 100%. m (b) How much farther must the car travel to encounter the next minimum in reception? 199 X Your response differs from the correct answer by more than 10%. Double check your calculations. m
