Doppler ultrasound is used to measure the speed of blood flow. The reflected sound interferes with the emitted sound, producing beats. If the speed of red blood cells is 0.100 m/s, the ultrasound frequency used is 5.00 MHz, and the speed of sound in blood is 1570 m/s, what is the beat frequency? If the speed of the red blood cells is v, the speed of sound in blood is u, the ultrasound source emits waves of frequency f, and we assume that the blood cells are moving directly toward the ultrasound source, then the frequency fr of reflected waves detected by the apparatus is given by fr Hz ft Express your answer in Hz. u+v u-v .
