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.
Problem 15.28 Review Constants Periodic Table Part A Research vessels at sea can create images of their surroundings by sending out sound waves and measuring the time until they detect echoos. The image of a shipwreck on the ocean bottom shown in (Figure 1) was made from the surface with 600 kHa utrasound What was the wavelength? Use values given in (Figure 2) i# necessary Express your answer with the appropriate units Figure K2 of2 X- 1 Value Units The...
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...
A doppler blood flow meter emits ultrasound at a frequency of 5.0 MHz. The speed of sound in human tissue is 1540 m/s. The blood is moving at 0.15 m/s. A. What is the frequency shift do to the motion of the blood (Ch. 15)? B. What is the frequency of the waves reflected off the blood? C. What is the beat frequency of the interference between the emitted and reflected waves?
