Concave Mirror
• C – Centre of Curvature
• V – Vertex (geometric centre of the
mirror)
• PA – Principal Axis (straight line through
C and V)
• F – Focus or Focal Point (the point where
the incoming rays will converge on the
Principal Axis
•f – Focal Length ( distance from F to V)
• NOTE: A Virtual Image of the
PRINCIPAL OBJECT only forms when the
object is in FRONT of the Focal Point

Convex Mirror
• C – Centre of Curvature
• F’ – Virtual Focus (point BEHIND
a convex mirror where incoming
parallel rays appear to converge
when reflected)
• Virtual Image in a convex mirror
will always appear smaller than the
object
QUESTION
• Why are there LESS applications
in your life for a convex mirror
