Waves from a radio station have a wavelength of 262 m. They travel by two paths to a home receiver 14.1 km from the transmitter. One path is a direct path, and the other 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.)

Solution Summary

The solution calculates the minimum distance from the mountain to the receiver so that the destructive interference is produced at the receiver.

Solution Preview

Since the mountain is directly behind the home receiver, the path difference in the two waves received at the home is
delta = 2d, where d is the ...
