Q1. Snell's Law describes the relationship between angles and refractive indices during:
Answer: Refraction of light at an interface between two media
Explanation: Snell's Law (n₁sinθ₁ = n₂sinθ₂) quantifies how a light ray bends when crossing the boundary between two media with different refractive indices, explaining why objects appear shifted when viewed through water or glass.
