A light beam travels along the ray determined by a unit vector L, strikes a flat surface
Chapter 12, Problem 83(choose chapter or problem)
A light beam travels along the ray determined by a unit vector L, strikes a flat surface at point P, and is reflected along the ray determined by a unit vector R, where 1 = 2 (Figure 21). Show that if N is the unit vector orthogonal to the surface, then R = 2(L N)N L R N L Incoming light Reflected light
