# 折射率

$n=\frac{c}{v}$

## 水波的相對折射率

$n_{AB} = \frac{\sin i}{\sin r}$

## 斯涅尔定律的特殊情况

$\frac{\sin i}{\sin r}=n$

## 介質的折射率

589.29 1.3330 [1]

1.31

1.661

Cytop 1.34 [9]
Sylgard 184 1.43

## 折射率是波长的函数

### 柯西公式

$n=A+\frac{B}{\lambda}+\frac{C}{\lambda^2}$[12]

### 康拉迪公式

$n=A+\frac{B}{\lambda}+\frac{C}{\lambda^{3.5}}$[13]

### Herzberger公式

$n=A+B*\lambda^2+\frac{C}{\lambda^2-\delta^2}+\frac{C}{(\lambda^2-\delta^2)^2}$[14]

### 肖特玻璃厂公式

$n=A+\frac{B}{\lambda}+\frac{C}{\lambda^2}+\frac{D}{\lambda^4}+\frac{E}{\lambda^6}+\frac{F}{\lambda^8}$[15]

### Sellmeier公式

$N^2-1=\frac{A*\lambda^2}{\lambda^2-D}+\frac{B*\lambda^2}{\lambda^2-E}+\frac{C*\lambda^2}{\lambda^2-F}$[16]
