How does the Snell's Law Refraction Calculator work?

Enter refractive indices of both media Then: Enter incident angle θ₁ Then: Solve for refracted angle θ₂ using Snell's law.

Can you give an example of how to use the Snell's Law Refraction Calculator?

Example: Input n₁ = 1 (air), n₂ = 1.5 (glass), θ₁ = 45° gives a result of θ₂ ≈ 28.1° (Light bends toward normal entering denser medium).

Is the Snell's Law Refraction Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Snell's Law Refraction Calculator?

Our Snell's Law Refraction Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
