Question:
Express refractive index of Medium 2 with respect to Medium 1 in terms of speed of light in two media.
Express refractive index of Medium 2 with respect to Medium 1 in terms of speed of light in two media.
Show Hint
The refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium. The bending of light depends on the relative speed in different media.

Solution and Explanation
The refractive index of Medium 2 with respect to Medium 1 is given by the formula: \[ n_{2/1} = \frac{c_1}{c_2} \] Where:
- \( c_1 \) is the speed of light in Medium 1,
- \( c_2 \) is the speed of light in Medium 2.
