Abstract
Simple harmonic vibration is the simplest and the most basic vibration, its application can be found in many different fields of physics. We can see the model of simple harmonic oscillator in our daily life, such as simple pendulum, torsion pendulum, LC circuit and the pointer of ammeter, etc. The vibration deserves comprehensive analysis in other fields.For example,the resonance from forced vibration is very important in building works. Wave is made by the transmission of vibration in medium. According to different standards, wave can be divided into different types. The study on the feature of waves leads to many kinds of subject, such as acoustic theory, electromagnetic waves theory, photonics theory and so on. In this thesis, we will discuss the feature of simple harmonic vibration and wave in mechanics, and use Visual Basic to describe the trajectory of all kinds of vibration and wave, the composition of vibration and the interference by drawing their pictures. We will change the parameter and condition to comprehend their feature more deeply.
