Hiệu quả của phương pháp vòng tròn trong giải bài toán dao động và sóng cơ học

Abstract

The mechanical oscillation and wave problems always play an important role in high school physics, and they are regularly seen both in the past years’ College Entrance Exams and in recent years’ High school National Exams with quite high difficulty. However, a large number of students have certain trouble with this kind of problem because they have yet to gain effective methods. This paper is to introduce circle-method as a useful method to find out solutions for mechanical oscillation and wave questions. It is hoped that the given examples will be meaningful tools for students and teachers in learning and teaching mechanical oscillation and wave problems, making good preparations for important exams.
