Question

Calculate the refractive index of the material of a glass slab. Giventhat the speed of light through the glass slab is 2 x 10 ki 8 m/s and inair is 3 x 10 ki power 8 m/s.​

Answer 1

Explanation:

Given Calculate the refractive index of the material of a glass slab. Given that the speed of light through the glass slab is 2 x 10 ki 8 m/s and in air is 3 x 10 ki power 8 m/s

• Given speed of light through glass slab is 2 x 10^8 m / s
• Speed of light in air is 3 x 10^8 m/s
• We need to find the refractive index of a glass slab.
• We know that refractive index μ = Speed in air / speed in medium
•                                                    = 3 x 10^8 / 3 x 10^8
•                                                    = 3/2
•                                        = 1.5

So the refractive index of the material of the glass slab is 1.5

Answer 2

Explanation:

Given speed of light through glass slab is 2×10⁸m / s.

Speed of light in air is 3x10⁸ m/s.

We need to find the refractive index of a glass slab.

We know that refractive index of material of glass slab = Speed in air / speed in medium.

= 3 x 10⁸ / 3 x 10⁸

= 3/2

= 1.5
