Question

If the speed of light in medium-1 and medium-2 is 2.5*10⁸ m/s and 2*10⁸ respectively. Then the refractive index of medium 1 with respect to medium 2 is what
Pls guys tell fast I have exam in an hour

Answer 1

Answer:

Refractive index of medium 1 with respect to medium 2

= speed in medium 2 / speed in medium 1

Refractive index = 4/5 = 0.8

Hope it helps

Answer 2

answer : refractive index of medium-1 with respect to medium - 2 is 4/5

given, speed of light in medium - 1 , v₁ = 2.5 × 10^8 m)/s

so, refractive index of medium - 1, μ₁ = 3 × 10^8/2.5 × 10^8 = 1.2

speed of light in medium - 2 , v₂ = 2 × 10^8 m/s

so, refractive index of medium-2, μ₂ = 3 × 10^8/2 × 10^8 = 1.5

refractive index of medium - 1 with respect to medium - 2, ¹μ₂ = μ₁/μ₂

= 1.2/1.5 = 4/5
