Red light is incident in air on a 30° -60° - 90 ° prism as shown. The incident beam is directed at an angle of ₁ = 47.9⁰ with respect to the horizontal and enters the prism at a height h = 27 cm above the base. The beam leaves the prism to the air at a distance d = 67.5 along the base as shown. 52.2 30⁰ 1.596 1) What is 2, the angle the beam in the prism makes with the horizontal axis? 01 d degrees Submit 2) What is n, the index of refraction of the prism for red light? 12.34485142 Your submissions: 52.2 ✓ Computed value: 52.2 Submitted: Tuesday, November 15 at 11:03 AM Feedback: Your answer has been judged correct; the exact answer is: 52.4776287536106.
