  • Plane mirrors
  • Description of virtual image that forms behind mirror.
  • Do ray tracing of object with dimension traveling to the eye from the mirror and the virtual image that forms
  • Do another ray tracing of multiple rays emanating from an object to the mirror and show the virtual image as convergence of reflected rays.
  • Define magnification as ratio image size to object size as well as ratio of image distance to object distance.

  • Problem with tree in reflection of plane mirror. How far do you have to stand from a 20 m tall tree to see its reflection in a 20 cm tall mirror if the mirror is 1 m from your eye?
  • Description of rear view mirror and its nighttime function. Descrption of passenger side mirror as a convex mirror. Show how concave and convex mirror images form as a function of distance to the object. Show how radius of curvature is found as a cutaway from a sphere.
