The Refraction Calculator helps determine the angle at which a light ray bends when passing from one medium to another, based on Snell’s Law. It uses the equation n1sin⁡(θ1)=n2sin⁡(θ2)n₁ \sin(θ₁) = n₂ \sin(θ₂)n1​sin(θ1​)=n2​sin(θ2​), where n1n₁n1​ and n2n₂n2​ are the refractive indices of the two media, θ1θ₁θ1​ is the angle of incidence, and θ2θ₂θ2​ is the angle of refraction. By entering these values, the calculator instantly computes the bending angle of light as it moves between materials like air, water, or glass. This tool is useful for physics students and educators studying optics, refraction, and light behavior across different materials.
