Hi Dick, Thanks, yes, it is a normal to the plane and not a unit normal.

Using the fact that the incident ray and reflected ray make equal angles to the Normal to the plane of the reflecting surface, we can compute the normal to that plane with the formula, Unit Normal vector N, <N> = (-(Unit Incident vector, I) + (Unit Reflected Vector, R))/2 which is, N =...
