Snell's Law of refraction is expressed as:
Q1. Snell's Law of refraction is expressed as:
Answer: n₁sinθ₁ = n₂sinθ₂
Explanation: Snell's Law describes the relationship between the angles of incidence and refraction when light passes between two media of different refractive indices: n₁sinθ₁ = n₂sinθ₂, where n₁ and n₂ are the refractive indices of the first and second medium respectively, and θ₁ and θ₂ are the angles measured.
