摘要
根据夫琅禾费衍射条纹特点 ,以高等数学为工具 ,采用对观察屏上各点的光强进行计算的方法 ,对衍射条纹分析对比研究 ,计算结果与实验结果得到了很好的吻合 ,与其它分析方法相比较 ,光强计算法通过对各级明纹光强的准确对比 ,不仅更能客观地反映出明、暗纹产生的原因 ,同时对光的波动性有一个进一步的认识。
Based on Fraunhofer's theory,the article analyzes the diffraction strip by computing light's intensity on each point of the screen.The computing result identifies with that of the experiment.Compared with others, the method can not only more objectively show the reason of the appearance of light and dark strips,but promote the understanding of light's waving by accurately contrasting light's intensity.
