常用折射率表

1、确定折射率:光从真空射入介质发生折射时，入射角irn简称“折射率”。它表示光在介质中传播时，介质对光的一种特征。公式:n=sin i/sin r=c/v1不同的折射率；在对可见光为透亮的媒质内，折射率常随波长的减小而增大，即红光的折射率最小，紫光的折射率最大。通常所说某物体的折射率数值多少1.331.552.421.51.9，是指对钠黄光589310-10而言。相对折射率:12 发生折射时，入射角 1 与折射角 2 的正弦之比n212示在两种各向同性介质中光速比值的物理量。公式:n21=sin 1/sin 2=n2/n1=v1/v2光学介质的一个根本参量。即光在真空中的速度c 与在介质中的相速

2、v 之比真空的折射率等于 1，两种介质的折射率之比称为相对折射率。例如，第一介质的折射率为n1，其次介n2，则n21n2n1质对真空的相对折射率。于是折射定律可写成如下形式 . n1sin in2sin t，折射率较大的称光密介质，折射率较小的称光疏介质。 r r导率。折射率还与波长有关，称色散现象。手册中供给的折射率数据是对某一特定波长而言的通常1.00027。在工程光学中常把空气折射率当作1，而其他介质的折射率就是对空气的相对折射率。液体介质常用临界角法阿贝折射仪；气体介质则用周密度更高的干预法瑞利干预仪。常用物体折射率表空气1.0003玻璃，锌冠1.517氯化钠盐21.644液体二氧化碳
