is the speed of light in a material The bigger the refractive index, \(n\), the slower the light travels in that material - ie the smaller \(v_{2}\) is. Light of frequency \(4.6\times 10^{14} ...

In general, the refractive index varies based on the frequency of the light as well, thus different colors of light travel at different speeds. High intensities also can change the refractive index.

A ray of blue light of frequency \(4.8 \times {10^{14}} Hz\) is incident on the surface of a piece of clear plastic as shown. For this light the refractive index of the plastic is \(1.48\).
