About this app

Refractix is an optics tool that demonstrates Snell's Law through interactive visualizations. Observe how light bends when passing between different media and explore the conditions that lead to total internal reflection.

Key Features:
Interactive refraction demo with real-time ray visualization on Canvas
Adjust the incident angle from 0° to 90° and watch the refracted ray update instantly
Select from 8 common optical media including Vacuum, Air, Water, Glass, Diamond, Ice, Ethanol, and Sapphire
Critical angle calculator showing the exact angle at which total internal reflection occurs
Behavior indicator that explains whether light refracts, reflects, or travels along the interface
Media comparison tool with preset pairs and custom refractive index input
Complete formula reference covering Snell's Law, critical angle, and total internal reflection
Reference table of common refractive indices for quick lookup

All calculations are performed locally on your device — no account, no internet required for core features.
