Question

if the refractive index of three materials is given as a>b>c.then the correct order of spedd of lighgt in given material medium is

Answer 1

Answer:

correct order of speed of light is a<b<c

Answer 2

Answer:

The correct order of speed of light in a given material medium is c>b>a.

Explanation:

This question can be directly solved if we know the relation between the refractive index of the medium and the speed of light in that medium.

Hence, the relation which we are going to use is:

The refractive index of a material(μ)=

                                speed of light in vacuum(c)$/$speed of light in that medium(v)

c=3 ×$10^{8}$ m/s     (it is a constant value)

μ∝1/v

So, the order of speed of light will be opposite to the values of μ

The given order of μ is a>b>c.

And the order of speed of light will be

c>b>a.
