Reflection
Interactive simulation — adjust parameters and watch the visualization update in real time.
How it works
Geometric reflection: angle of incidence equals angle of reflection (measured from the surface normal). Plane mirrors give a left–right reversed virtual image. Concave and convex spherical mirrors are drawn with paraxial principal rays and focal point F at half the radius of curvature.
Key equations
θᵢ = θᵣ (specular reflection)
Spherical mirror: f = R / 2
