The ratio of thickness of plates of two transparent medium A and B is 6 : 4. If light takes equal time in passing through them, then refractive index of A with respect to B will be

The ratio of the thickness of the strips of two transparent media A and B is 3:2 , if light takes the same time in passing through both of them , then what is the refractive index of B with respect to A ?

Two transparent media A and B have thickness ratio 1 : 2. The time taken by light in passing through A and B is same. Find the refractive index of B w.r.t A.

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum. What is the refractive index of the medium?

If the refractive index of medium b with respect to medium a and that of medium c with respect to medium b are given, then the refractive index of a medium c with respect to a medium a can be found by using the relation n_(ca)=n_(ba)xx ____.

A light ray enters from medium A to medium B as shown in Figure. The refractive index of medium A relative to B will be
