About this calculator
The Prism Refraction Angle Calculator calculates the refraction angle, which depends on the angle of incidence, the angle of deviation and the angle of emergence.
What is refraction?
When light passes through a prism, it undergoes refraction, causing the light to change direction based on the geometry and refractive index of the prism material. The amount and angle of bending depend on the refractive index of the prism material, which determines how much the light slows down inside the prism compared to air.
What affects the refraction angle?
The refraction angle is equation to the sum of the angle of incidence and angle of emergence, minus the angle of deviation.

How to verify a calculation
Engineering calculations require clarity, precision, and professionalism. Here are some best practices we use at CalcTree:
- Technical Requirements: Start with boundary conditions, units, sign conventions, and design standards.
- Check the Math: Review the calculation step-by-step. Clarify unusual steps, compare results with hand calculations or tools, and test with multiple examples.
- Peer Review: Have an independent reviewer check for logic, accuracy, and compliance.
For more on verification, see CalcTree’s internal methods.
