Question

Refractive indices of four media A,B,C,D are 1.33, 1.50, 1.52, 2.4 respectively.
a)In which medium speed of light is minimum?
b)Which medium is a most optically dense. Give reasons for your answer

light reflection & refraction class10

Answer 1

Answer:

a) *medium having refractive index 2.4

b) media having refractive index 2.4*

Explanation:

we know that higher the refractive index higher the optical density and lower the speed so by using this formula I have answered that in medium having refractive index 2.4 the light of speed is minimum and it is optically denser at compared to other medium
