A person driving at V = 16.4 m/s crosses the line connecting two radio transmitters at right angles, as shown in the figure below. L1 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, L1 = 440 m and L2 = 171 m away from the %3D transmitters, the radio picks up a maximum net signal. What is the longest possible wavelength of the radio waves?

Question
(a) 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, 1 = 440 m and 2 = 171 m away from the transmitters, the radio picks up a maximum net signal. 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 the previous problem.
