Problem

A ray of light passes through three media as shown in the figure. How are the speeds of light in these media related? [Figure: Light ray passing through three different media with different angles of refraction] a) v₃ > v₂ > v₁ b) v₁ > v₂ > v₃ c) v₂ > v₁ > v₃ d) v₃ > v₁ > v₂ e) v₁ > v₃ > v₂
