Question

Find the absolute refractive index of a medium in which light travels with a speed of 2.14×10reised 8 m/s

Answer 1

Answer:

Explanation:

REFRACTIVE INDEX= 3*10^8/ GIVEN VELOCITY

REFRACTIVE INDEX= 3*10^8/2.14*10^8

REFRACTIVE INDEX= 1.401 .

HOPE THIS HELPS.

Answer 2

Answer:

1.401

Explanation:

Refractive index (of substance with respect to air) =

        Speed of light in air    

Speed of light in substance

so it becomes 1.401

also as it is a ratio of two substances, it doesn't have a unit

hope it helps :D
