Concave Mirror

3. Grade 10 Applied Science – Curved Mirrors
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

6. Grade 10 Applied Science – Curved Mirrors
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
