question 24

Multiple Choice

When light is totally polarized by reflection at an interface between two materials where the index of refraction for the incident medium is n₁ and for the other is n₂, the incident angle is given by θ = tan^-1(n₂/n₁) . This equation holds

• A) only when n₂ > n₁.
• B) only when n₁ > n₂.
• C) only when n₂ > n₁ + 1.
• D) only when n₂ < n₁ + 1.
• E) for all values of n₁ and n₂.
