PHY2061 R. D. Field Department of Physics chp39_3.doc University of Florida Geometric Optics Fermat’s Principle: In traveling from one point to another, light follows the path that requires minimal time compared to the times from the other possible paths. Theory of Reflection: Let t AB be the time for light to go from the point A to the point B reflecting off the point P . Thus, t c L c L AB =+ 11 12 , where Lx a Ld x b 1 22 2 =− + () .
