(a)
There are two (2) main types of mirrors
(a)
Always erect/upright

Inverted
Real Image
Virtual Image
Formed by actual intersection of light rays
Real
Virtual
Formed due to imaginary intersection(Light rays appear to be originating from a point but does not actually meet)

An image formed by reflection may be ____ or ______.
(a)
Have curved reflecting surfaces. Is formed when you cut out a piece from a sphere and make either of the surfaces reflective. have two (2) kinds- Concave and Convex Mirrors
(a)
Have a flat reflecting surface and produce image.
(a)
It is the midpoint of a spherical mirror. It is represented by the letter ‘V’.
(a)
It is the distance between the pole of a spherical mirror and the center of the curvature. The radius of curvature is denoted by “R’.
(a)
It is the diameter of the reflecting surface of a spherical mirror.
(a)
It is the center of the sphere of which the mirror is a part. The center of curvature is denoted by “C’.
(a)
It is a point on the principal axis where the light rays parallel to the principal axis converge (if it is a concave mirror) or appear to diverge (if it is a convex mirror) after getting reflected from the mirror.
(a)
It is denoted by the letter ‘f’. It is the distance between the center of the mirror and the focal point of the mirror. It is the point where a parallel beam of light
converges or diverges.
(a)
The straight line passing through the pole of a spherical mirror and the center of curvature.
