Two totaiton vector methods to study the problem of plane harmonic vaves
How to correctly use the vibration rotation vector and the spatial(wave)rotation vector to study the problems of plane simple harmonics is a difficult problem in the teaching of university physics.By comparing the two rotation vectors in detail,analyze the similarities and differences between the two rotations in terms of wave function and waveform graph,and summarize the considerations for using two rotation vectors to solve the problems of plane simple harmonics.The results show that the application of the two rotation vectors greatly reduce the difficulty of solving the problems of plane simple harmonics.When applying,the type of rotation vector should be specified and its characteristics should be noted to avoid confusion and errors.
