Question

calculate the speed of light in a medium of refractive index 2.4 given speed of light ​

Answer 1

Answer:

Refractive index = speed of the light in air / speed of the light in medium. Speed of light in medium = 3×10^8 / 2.4 m/s. = 1.25 × 10^8 m/s

Answer 2

Speed of light in medium of refractive index 2.4 = 3×10^8/2.4.

= 1.25 × 10^8
