During trials of a new submarine, its speed is measured with an underwater sonar gun anchored to the ocean floor. The gun emits sound waves at a frequency f, and these waves reflect off the surface of the submarine and return to the source at a frequency f' Z f. If the submarine is receding from the sonar gun at speed v, derive an expression for f' in terms of f, v, and c (the speed of the waves through water).
