Q) If the velocity of blood flow in the aorta is about 0.32 m/s, what is the pulse frequency you would expect if the 4.3 MHz ultrasound was directed along the blood flow and the waves were reflected from the red blood cells? Suppose waves travel at a speed (1.54 x 103 m/s) 17.88KHZ 1788KHZ 1788HZ 17.88H2 178.7 Hz
