A Doppler ultrasound is used to measure blood flow speeds, for instance, in a patient's artery. Assume the probe emits ultrasound waves at a frequency of 5 x 1O^6 Hz and the speed of sound in human tissue is 1540 m/s. (a) Why is the Doppler effect the basis of the mechanism of an ultrasound machine? (b) What is the frequency, f" received by the probe if the beat frequency, that is, the frequency shift following reflection, is 400 Hz...

An echocardiogram uses 4.4 MHz ultrasound to measure blood flow in the aorta. The blood is moving away from the probe at 1.6 m/s . A. What is the frequency shift of the reflected ultrasound? Use values given in the table if necessary. Enter a positive value if the received frequency is higher than the emitted frequency, and a negative value if the received frequency is lower than the emitted frequency.
