An echocardiogram uses 4.4 MHz ultrasound to measure blood flow in the aorta. The blood is moving away from the probe at 1.2 m/s. The speed of sound Medium Air (0 C) Air (20 C) Heluim (0 C) Ethyl alcohol Water Human tissue (ultrasound) Lead Aluminium Granite Diamond Speed (m/s) 331 343 970 1170 1480 1540 1200 5100 6000 12,000 What is the frequency shift of the reflected ultrasound? Use values given in the tab necessary. Enter a positive value if the received frequency is higher than the emitte frequency, and a negative value if the received frequency is lower than the emitted Af = N An echocardiogram uses 4.4 MHz ultrasound to measure blood flow in the aorta.
