Question

Ultrasound waves are used to measure blood- flow speeds. Suppose a device emits sound at 500 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 arter- ies at 2.0 cm/ s directly away from the sound source? How can you connect this analogue to the radars for example?

Answer 1

Answer: if 500 kHz was to be used in sound of a human tissue. Yes it would be taken into 1540 m/s. BUT, if you were to add 500 plus 1540 then you can get your answer
