A Doppler flow meter uses ultrasound waves to measure
Chapter 13, Problem 56P(choose chapter or problem)
(II) A Doppler flow meter uses ultrasound waves to measure blood-flow speeds. Suppose the device emits sound at \(3.5 \mathrm{MHz}\), and the speed of sound in human tissue is taken to be \(1540 \mathrm{~m} / \mathrm{s}\). What is the expected beat frequency if blood is flowing in large leg arteries at \(2.0 \mathrm{~cm} / \mathrm{s}\) directly away from the sound source?
