 \$n_1\$ and \$n_2\$ are the [[wp>Refractive_index |Refractive Indices]] of the media.  They are defined as the ratio of the speed of light in vacuum to the speed of light in the media \$\left(n = \frac{c}{v}\right)\$.  For example, if \$n = 2\$, then the speed of light is twice as //slow// in the medium as it is in vacuum.  The bigger \$n\$ is, the slower the speed.  \$n = 1\$ means that the speed is the same as the speed of light in a vacuum.
