Simulating Reflection from a concave mirror.

Hello Everyone.

The problem at hand is to simulate reflection a photon undergoes from a concave surface(mirror). The known parameters are Radius of curvature and center of curvature of concave mirror and various positions of the photon before it hits the mirror surface.

The above query is part of Monte-Carlo simulation in which a photon incident into a medium makes number of moves and when it encounters the mirror, it must reflect back and continue its journey.

Any help would be appreciable.

I’ve not used the surfnorm function much (and never for ray-tracing). You may find it helpful.
