Question 1 (10 points) A light ray travels from glass (n = 1.50) to air. If the angle of incidence is 32.5°, what is the angle of refraction? 21.0° 39.5° 41.8° 53.7° The question is misleading because the light ray will be totally reflected. Question 2 (10 points) A light ray travels from air to glass (n = 1.50). If the angle of incidence is 32.5°, what is the angle of refraction? 21.0° 39.5° 41.8° 53.7° The question is misleading because the light ray will be totally reflected.

Step 1
Here n₁ = 1.50 (glass), θ₁ = 32.5°, n₂ = 1.00 (air). sinθ₂ = (1.50)·sin(32.5°) ≈ 1.50·0.53730 ≈ 0.80595. Show more…
