Question

108. ••Medical An ultrasonic scan uses the echo waves
coming from something moving (such as the beating heart
of a fetus) inside the body and the waves that are directly
received from the transmitter to form a measurable beat
frequency. This allows the speed of the internal structure
to be isolated and analyzed. What is the beat frequency
