Step 1

Refractive index of a material is defined as the ratio of speed of light in vacuum to the speed of light in the medium. equation (I) represents the expression for refractive index.

Step 2

let v_{A} be the speed of light in medium A, and v_{B} be the speed of light in medium B. The speed of light in medium A is 1.4 times the speed of light in medium B.

Step 3

Take the ratio of refractive index of medium A and B, and su...
