Question

The speed of light in medium A is 2.25 x10 m/s and that in medium B is 2 x 10 m/s. A ray is travelling from medium A to B. Find the refractive index of medium B with respect to medium A.​

Answer 1

Explanation:

Roads are easy to build and maintain as compare to railways.

Roads are easy to build and maintain as compare to railways.Constructions cost of roads is much lower that of railway lines.

Roads are easy to build and maintain as compare to railways.Constructions cost of roads is much lower that of railway lines.Roads as compare to railways lines can negotiate higher gradients of slopes easily and as such can traverse mountains like Himalayas.

Answer 2

Explanation:

WE KNOW THAT THE REFRACTIVE INDEX OF A MEDIUM = vmc

where, vm = speed of light in medium = 2.25×108m/s

and,C = the speed of light = 3×108m/s

therefore, the refractive index of medium = 2.25×1083×108= 1.33
