Homework Statement
Ultrasound waves are used to measure blood-flow speeds. Suppose a device emits sound at 450 kHz, and the speed of sound in human tissue is taken to be 1540 m/s. What is the expected beat frequency if blood is flowing normally in large leg arteries at 3.0 cm/s directly away from the sound source?
_____Hz
Homework Equations
F2 = F1 / ( 1 + ( Vs / V ) )
The Attempt at a Solution
F2 = 450000 / (1 + ( 1540 / 343 ) )
F2 = 81970.26 Hz
