Document Summary

Half-silvered mirrors (cid:1680) glass coated by a thin layer of silver that can reflect half and transmit the other half of light. Spherical mirrors -- pieces of reflecting material in the shape of part of the surface of a sphere. Paraxial or near axis rays give us a pretty good picture of what actually happens. Convex mirrors (cid:1679) a mirror that bulges toward the source of light. For spherical mirrors, the focal length is just one half of the radius of the sphere. Ray one rule (cid:1679) all raise incident parallel to the axles are reflected so that they appear to be coming from the focal point. Ray 2 rule (cid:1679) (cid:1679) all rays that when extended pass through c are reflected back on themselves. Ray three rule -- all rays that when extended pass through f are reflected back parallel to the axis. A convex mirror is a wide angle mirror.
