Refraction Angle with Snell Law
Apply refraction for flat boundary between two materials.
Your numbers
Angle after refraction
Ideal SI-unit model for learning. Real components, tolerances, losses and safe operating limits need separate checking.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use n₁sinθ₁ = n₂sinθ₂. n₁ and n₂ na incident and transmitted refractive indices; θ₁ and θ₂ na angles from di normal. Enter and read angles for degrees. If refraction no get real angle, di result show total internal reflection.

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
