对一类菲涅耳公式的实验研究

Experimental Study for One Kind of Fresnel Formulas

菲涅耳公式用于描述不同折射率的介质之间的行为,是光学中的重要公式,用来解释反射光的强度、折射光的强度、相位与入射光的强度关系。为了解释实验中发现的光学现象,该文导出了光在介质分界面反射时的菲涅耳公式,通过实验的对比研究,在误差允许的范围内,由新公式得出的理论值与实验结果相符合,从而验证了这类菲涅耳公式的准确性。

Fresnel formulas is used to described different behaviors between the refractive index of the medium. Fresnel formulas is one of the most important optical formulas used to explain the intensity of the reflected and refracted light and the relationship between the phase and the intensity of the incident light. In order to explain an optical phenomenon during our experiment,we deduce Fresnel formulas which describe light＇s reflections in interface between mediums in this paper. To ascertain the accuracy of the kind formula,we carry out an experimental research and get the theory value. With the allowable error range,the computational results are fitted well with the experimental ones,which prove the accuracy of this kind formula.
