Question

Velocity of light in air is 3x10^8 m/s while its velocity in a medium is 2.5x10^8 m/s.

Find the refractive index of this medium.​

Answer 1

Answer:

7.5×10^16

Explanation:

refractive index n = cv,

given c =3x10^8 m/s and v = 2.5x10^8 m/s in question.

n = 3x10^8×2.5x10^8

= 7.5×10^16

ஃ refractive index n = 7.5×10^16
