| Abstract: | Physical knowledge and real life are closely related, and using uhrasound to measure speed is a typical example. If this kind of problem is solved by law of kinematics, it will be quite complex. However, if it is solved by Doppler effect, it win be very simple. This paper makes a theoretical analysis of the principle of Doppler effect and the calculation formulas, and compares the method of applying the law of kinematics to the corresponding examples with that of applying Doppler effect to the examples. |
