Question

Light enters from air to diamond having refractive index 2.42. calculate the speed of light in diamond.

Answer 1

Answer:

Explanation:

refractive index  is diamond  with  respect to air  = v air / v  diamond

v diamond = 3 * 10^8  /2.42

= 1.24 * 10^8  m/s

Answer 2

Answer:

Explanation:

We know,

Refractive index of medium=Speed of light in air/Speed of light in medium

Hence,

Speed of light in diamond=(3*10^8)/2.42=1.24×10^8m/s

Hope you understood
