Fermat's Principle a. Two poles of heights m and n are separated by a horizontal distance d. A rope is stretched from the top of one pole to the ground and then to the top of the other poke. Show that the configuration that requires the least amount of rope occurs when 6, = 0, (see figure). (a) b. Fermat's Principle states that when light travels between two points in the same medium (at a constant speed), it travels on the path that minimizes the travel time. Show that when light from a source A reflects off a surface and is received at point B, the angle of incidence equals the angle of reflection, or O, = 0, (see figure). (b) A Medium 1 Medium 2
