A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in the figure below. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L- 120 m from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y- 20 m to his side. A boat on the river sounds its horn. To person A, the sound is loud and clear. To person B, 1.70 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center. sound is barely audible. The principal wavelength of the sound waves is m

Figure P36.35 shows a radio-wave transmitter and a receiver separated by a distance d = 50.0 m and both a distance h = 35.0 m above the ground. The receiver can receive signals both directly from the transmitter and indirectly from signals that reflect from the ground. Assume the ground is level between the transmitter and receiver and a 180 phase shift occurs upon reflection. Determine the longest wavelengths that interfere (a) constructively and (b) destructively. Figure P36.35 Problems 35 and 36.
