Refractive Index
Snell's Law
- Refractive Index (n) = \(\frac{\sin(i)}{\sin(r)}\)
Refractive Index Practical
Equations
\[n=\frac{c}{c_{s}}\]
The notation for Refractive index
\(\(_{1}n_{2}=\frac{n_{2}}{n_{1}}\)\)
So:
\(\(_{\text{water}}n_{\text{glass}}=\frac{n_{\text{glass}}}{n_{\text{water}}}\)\)
Example:
When \(n_{water}=1.33\) and \(n_{\text{glass}}=\frac{1.50}{1.33}=1.127=1.13\) (to 3.sf)
