If the refractive index of medium 2 with respect to medium 1 is greater than 1 what does it implies?

Refractive index of medium= $\frac{\mathrm{speed} \mathrm{of} \mathrm{light} \mathrm{in} \mathrm{air} \mathrm{or} \mathrm{vacuum}}{\mathrm{speed} \mathrm{of} \mathrm{light} \mathrm{in} \mathrm{medium}}$

That means the speed of light is inversely proportional to the refractive index.

Therefore, if the refractive index of medium 2 with respect to medium 1 is greater than 1 then it implies that the speed of light in medium 2 < speed of light in medium 1.
