A ray of light is passing from a transparent medium 1 to another transparent medium 2 (i) Speed up (ii) slows down.
A ray of light is passing from a transparent medium 1 to another transparent medium 2 (i) Speed up (ii) slows down. In each case, state whether the refractive index of medium 2 is equal to, less than or greater than the refractive index of medium 1.

In case (i) the refractive index of the medium 2 is less than the refractive index of medium 1 because the ray of light speeds up.
While in case (ii) the refractive index of the medium 2 is greater than the refractive index of medium 1 due to because here the ray of light slows down.
