A receiver located in front of a sheer cliff as shown in the figure picks up interfering signals from a nearby 265 kHz transmitter. One signal travels directly from the transmitting antenna to the receiver, and the other first travels to and bounces off the cliff. (a) What is the wavelength of the signal? λ = km (b) For what minimum possible distance between the cliff and the receiver will the two waves interfere constructively at the receiver? Transmitting Cliff Receiver antenna Use c = 2.998 x 108 m/s.
