Question

light enter from air into diamond which has a refractive index of 4.2 calculate the speed of light in air is 3.0×108 m/s ​

Answer 1

Answer:

Refractive index of diamond = 4.2

Speed of light in air = 3.0 × 108 m/s

We know that,

Refractive index of diamond

= speed of light in air/ speed of light in

diamonds

4.2 = 3.0× 108/ speed of light in diamonds.

Speed of light in diamonds = 3.0× 108/4.2

= 1.6666...×108 m/s.

For know answers is correct or not, calculate yourself...
