16.3 §

• Concave Mirror - Mirror that curves inwards
• Convex Mirror - Mirror that bulges outwards
• Center of Curvature - Center of the sphere of which the curved mirror is a section
• Principal Axis - Drawn through the center of curvature and the midpoint of a curved mirror
• Focal Point - The point at which rays reflecting from the surface of a mirror converge
• Focal Length - The distance from surface of the curved mirror to the focal point
• Focal length for a Concave Mirror with radius (R)
  • focal length = x radius of curvature
  • f = R
  • SI Unit: m
• Focal length for a convex mirror of radius R
  • focal length = - x radius of curvature
  • f = - R
  • SI Unit: m
• The Mirror Equation

• Magnification
  • magnification = = - ()
  • m = = -
