Homework Help: Physics

The waves from a radio station can reach a home receiver by two paths. One is a straight-line path from transmitter to home, a distance of 21.0 km. The second path is by reflection from the ionosphere (a layer of ionized air molecules high in the atmosphere). Assume this reflection takes place at a point midway between receiver and transmitter and that the wavelength broadcast by the radio station is 350 m. Find the minimum height of the ionospheric layer that could produce destructive interference between the direct and reflected beams. (Assume that no phase changes occur on reflection.)
