In an experiment to demonstrate interference, you connect two antennas to a single radio receiver. When the two antennas are adjacent to each other, the received signal is strong. You leave one antenna in place and move the other one directly away from the radio transmission tower. How far should the second antenna be moved in order to receive a minimum signal from a station that broadcasts at 103.4 MHz?
Waves from a radio station have a wavelength of 250 m. They travel by two paths to a home receiver 20.0 km from the transmitter. One path is a direct path, and the second is by reflection from a mountain directly behind the home receiver. What is the minimum distance from the mountain to the receiver that produces destructive interference at the receiver? (Assume that no phase change occurs on reflection from the mountain.)
Anna Litical is listening to WBBM - 780 KHz on the radio dial - when she observes destructive interference occurs due to the reflection of radio waves off a plane that is directly above her home. WBBM broadcasts from a location of about 40 miles from her home. Determine the closest possible distance that the plane could be overhead and determine the next three possible heights of the plane. (Assume that the reflected wave does not undergo a phase change upon reflection off the plane.)
