 k -- vector path of laser light n -- vector normal to surface of prism a -- arbitrary vector point on the plane of the prism b -- critical point that the k vector traverses; is the origin to start, then uses different coordinates each time the k vector traverses a new medium (air vs. prism) where n is the unit vector for the normal. Solve for alpha and plug into (b + alpha*k) which gives the new value for b. Repeat this process over the entire path of k. Prism Tilting -- See snell's law4.nb |
