Q1. Light travels from air (n=1) into glass (n=1.5). The light bends:
Answer: Towards the normal
Explanation: When light passes from a less dense medium (air, n=1) to a denser medium (glass, n=1.5), it slows down and bends towards the normal according to Snell's Law: n₁sinθ₁ = n₂sinθ₂. Since n₂ > n₁, the refracted angle is smaller, meaning the ray bends toward the normal.
