Ultrasound probe emitting sound waves toward moving blood cells.
Ultrasound probe emitting sound waves toward moving blood cells.
An ultrasound diagnostic probe held stationary against a patient's skin emits a sound wave of frequency \(5.00 \text{ MHz}\) through tissue where the speed of sound is \(1500 \text{ m/s}\). The sound wave travels directly along an artery toward blood cells that are moving away from the probe. The blood cells receive the ultrasound wave at a shifted frequency of \(4.995 \text{ MHz}\). What is the speed of the blood flow?
