Express refractive index of Medium 2 with respect to Medium 1 in terms of speed of light in two media.
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.
