1820年奥斯特电产生磁 1831年法拉第磁产生电 变化的磁场激发电场

1、伽利略变换的困难 （1)电磁场方程组不服从伽利略变换 （2)光速c （3)高速运动的粒子 2、迈克耳孙-莫雷实验 测量以太风零结果

光在传播过程中遇到障碍物,能够绕过障碍物的边缘 前进这种偏离直线传播的现象称为光的衍射现象

一、光源 1、光源的发光机理 光源的最基本发光单元是分子、原子能级跃迁辐射

Graphlte works as a lubrlcant because the planes,held together by strong chemlcal (covalent) bonds between the carbon atoms, can sllde across each other wlth only J.M.H.L.S. weak Van der Waals bonds between the planes belng broken

The models of specific heat based on equipartition of energy and including rotational degrees of freedom as well as translational are able to explain specific heats for diatomic molecules. The departure from this model in the case of polyatomic molecules indicates vibrational involvement
