Let ^ ₁ ^ and ^ ₂ ^ be the refractive indices of two media. ' v ₁ ^ and ' v ₂ ' are the velocities of light in the media respectively. Which one of the following relations is TRUE?

Options

  1. A₁ v ₁= ₂ v ₂
  2. B₂ v ₁= ₁ v ₂
  3. C₁ v ₁²= ₂ v ₂²
  4. D₂² v ₁= ₁² v ₂

Correct answer

A. ₁ v ₁= ₂ v ₂

Step-by-step solution

₁= c v₁ ₂= c v₂ ₁ v₁= ₂ v₂
