Please answer all of these questions with brief explanations. Thank you! Name: Doppler ultrasound PROBLEM 4-8 points Ultrasound is the name we give to sound waves that have a higher frequency than 20 kHz, which is the maximum frequency our ears can respond to. For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). 2 points] (a) Ultrasound equipment for diagnostic imaging typically uses frequencies between 1...
