15. Convex Mirror
O
Cutting point of
the main axis to
the convex
mirror
P
Center point of
the mirror
curvature
F
Focal point of
the mirror
Main/Principal
Axis
R
Radius of the
mirror curvature
f
Focal length
of the mirror

16. A convex mirror has a property of
diverging light (divergent).
Convex mirror also has three specific
properties as follow :
1. If the incident ray paralleled to
the principal axis, it will reflected as
if it from the focal point (F).
P
2. If the incident ray passed through
the focal point (F), it will reflected
parallel to the principal axis.
3. If the incident ray passed through
the curvature center point (P), it will
reflected as if it from the curvature
center point (P).
