Objective (1) Understand the principles of the ultrasonic Doppler effect and its application in speed measurement. (2) Design and build an ultrasonic Doppler speedometer to measure the velocity of a moving object. (3) Analyze experimental data and improve measurement accuracy. 2. Principle The ultrasonic Doppler effect states that when ultrasonic waves encounter a moving target (such as a small car or fluid), the frequency of the reflected wave shifts. The freque..."
