solve the following numericals
If the speed of light inglass is 2x 108 m/s, o
and that in air is 3x108m/s, calculate the
refractive abex index of the medium.​

Answer 1

Answer:

Given:

Speed of light in glass- v = 2 x 10^8 m/s

Speed of light in air- c = 3 x 10^8 m/s

To find:

Refractive Index of glass- μ

Formula:

μ = c/v

Solution:

μ = c/v

μ = 3 x 10^8 / 2 x 10^8

μ = 3/2

μ = 1.5

Answer:

The refractive index of glass is

${\boxed{\boxed{\mathbb{\purple{1.5}}}}}$

Hope this helps you.

Answer 2

Answer:

2/3m/s

Explanation:

Speed of air / Speed of light =3*10^8/2*10^8

=3/2m/s

=1.5m/s
