The below figure shows two transparent materials stacked on top of each other, having refractive indexes n₁ = 1.2 and n₂ = 1.55. In order for no light to escape at the material 2 - air interface, the angle ₁ shown in the figure should have the following condition: 0₁ > 0. Determine the angle 0, in degrees. 0₁ 021 nair Material 2 N₂ Material 1 n₁
