📊 Refraction — Bending at Boundaries
Figure 2: Refraction at an air-glass boundary — light bends toward the normal when slowing down
RULES: Fast → Slow = bends toward normal (e.g., air to glass). Slow → Fast = bends away from normal (e.g., glass to air). At 90° (perpendicular) = no bending, but speed still changes.
