Chapter 23, Problem 60SP
To determine the speed of a harmonic oscillator, a beam of sound is sent along the line of the oscillator’s motion. The sound, which is emitted at a frequency of 8000.0 Hz, is reflected straight back by the oscillator to a detector system. The detector observes that the reflected beam varies in frequency between the limits of 8003.1 Hz and 7996.9 Hz. What is the maximum speed of the oscillator? Take the speed of sound to be 340 m/s.

Male Rana catesbeiana bullfrogs are known for their loud mating call.The call is emitted not by the frog’s mouth but by its eardrums, which lie on the surface of the head. And, surprisingly, the sound has nothing to do with the frog’s inflated throat. If the emitted sound has a frequency of 260 Hz and a sound level of 85 dB (near the eardrum), what is the amplitude of the eardrum’s oscillation? The air density is 1.21 kg/m3.
