HW # 10 - Refraction of Light 8 [ Accessibility Mode Immersive Reader Down Handout Problems: 1. What is refraction? (b) In which direction is light refracted on passing obliquely from air or a vacuum into a denser substance? (c) What happens to the angle of refraction as the angle of incidence decreases from 45 to 097 2. When a ray of light moving within a block of Zircon enters a block of Lucite at an angle, it will bend the normal. 3. A ray passes from air into water at an angle of incidence of 50. Find the angle of refraction to the nearest degree. 4. When a ray traveling in air is incident upon medium X at an angle of 45, the angle of refraction is 290. What might medium X be? Show work (formula, substitution, units). 5. The diagram below shows a ray of light passing from medium X into air. What is the absolute index of refraction of medium X? Normal 30 .1 Medium X Air 60
