1.光由光疏介质斜射入光密介质,光向法线靠拢。
2.光过玻璃砖，向与界面夹锐角的一侧平移；光过棱镜，向底面偏折。
3.光到球面、柱面，半径是法线。
光的本性
1.双缝干涉条纹宽度：Δχ=Lλ/d。
2.用标准样板检查工件表面情况：条纹向窄处弯是凹，向宽处弯是凸。
3.增透膜的厚度为光在膜中波长的四分之一。
4.电磁波进入介质时，频率（和光的颜色）不变。光入介质：v=c/n，λ=λ0/n
原子物理
1.在磁场中的衰变：外切圆是α衰变，内切圆是β衰变，半径与电荷量成反比。
2.X变成Y经过几次α、β衰变？先用质量数求α衰变次数，在由电荷数求β衰变的次数。
3.平衡核反应方程：质量数和电荷数守恒。
4.1μ=931.5Mev
5.核反应总质量增大时吸能，总质量减小时放能。仅在人工转变中有吸能的核反应。
6.氢原子任一能级：E=Ep+Ek，E=-Ek，Ep=-2Ek量子数n增大，E增大，Ep增大，Ek减小，V减小，T增大。
