How this service works
Snell's law: refracted angle between two media (names or indices), critical angle and total internal reflection check.
Output
Returns the resolved refractive indices for both media (with recognized names like air, water, crown glass, diamond), the refracted angle in degrees, the critical angle (if applicable), a verdict on whether total internal reflection occurs, the Brewster angle, the speed ratio of light between the two media, the angular deviation, and a human-readable summary.
Example use cases
Fiber optic TIR threshold check
“I'm designing a fiber optic cable — what's the critical angle for total internal reflection at the boundary between crown glass (n≈1.52) and air, and if light hits at 35 degrees from the normal, does it reflect internally or escape?”
Gemstone brilliance analysis
“Light inside a diamond hits a facet at 20 degrees from the normal going toward air — does it undergo total internal reflection, and what's the critical angle for diamond?”
Underwater photography refraction
“A camera is in water filming something above the surface. If light from above enters the water at 60 degrees from the normal, what angle does it refract to inside the water?”

Endpoint
GEThttps://physics-calc.x402tookit.com/snell?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, physics-correct calculation of Snell's law refraction, including total internal reflection checks and Brewster angle — especially when working with named optical media (air, water, glass, diamond) rather than raw indices. Prefer it over generic math tools when the optics domain context and structured output (verdict, critical angle, summary) are needed.
Side effects
- Unknown medium name that cannot be resolved to a refractive index
- Incident angle outside 0–90 degrees range
- Missing required parameters (n1, n2, or incidentAngleDeg)
- Invalid or non-numeric index values causing parse failure
