Question: Problem 6: (20 pts.) Electromagnetic waves, such as television and radio waves, can reflect from nearby mountains or from airplanes, and the reflections can interfere

Problem 6: (20 pts.) Electromagnetic waves, such as television and radio waves, can reflect from nearby mountains or from airplanes, and the reflections can interfere with the direct signal from the station. Suppose you are 1250 m away from a radio station broadcasting radio waves at an unknown frequency f. One wave travels directly from the station to you. A second wave bounces off an airplane midway between you and the station a height 409 m off the ground. (Assume the wave is inverted upon reflection from the airplane.) If you observe destructive interference between those two waves, what is the lowest possible value for the frequency f? destructive but want Airplane 746.93 746.93 409 m mal Radio Station 625 You 1250 m
