Convex Mirror

• Convex mirror reflects light from outer curved
  surface
• Mirror reference points
• Center of curvature

• Focal point
• Convex mirror ALWAYS produces a virtual, reduced
  image
• Referred to as diverging mirrors
• Used when large field of view needed

• Reflections
• Rays parallel to principal axis reflect through
  focal point on other side of mirror!
• Rays through focal point reflect parallel to

  opposite side of mirror!
• Rays through center (along principal axis and
  through focal point) reflect back along same path
