16. REFLECTION AND REFRACTION PURPOSE: To show by means of ray tracing: a) The angle of incidence equals the angle of θ1 reflection θ1‘. b) The virtual image is the perceived location of the object behind the mirror. c) The angle of deflection is twice the angle through φ which a mirror is rotated. d) The index of refraction can be determined using Snell's Law. normal normal θ1 n1 n2 θ1 θ1‘ θ2 Law of reflection: Law of refraction (Snell’s Law): θ1 = n1sinθ1 = n2sinθ2 θ1‘ APPARATUS: Cardboard Ledger (11" X 17") Ruler Protractor, large Compass, pencil Straightedge Pencil, color Mirror, plane Pins, long Refraction cube
