| Abstract: | The paper demonstrates the fignres made by using the mathematical software "Mathematica"and analyses the effect of the frequency difference, amplitude ratio and phase difference of two simple harmonic upon the beat phenomenon. In addition , the research finds out the range of the frequency difference and amplitude radio of two simple harmonic motions which can produce clear beat phenomenon. |
