Spherical Mirrors
Spherical Mirror :A curved mirror formed by a part of a hollow glass sphere with a reflecting surface (created by depositing silver metal) is also referred to as a spherical mirror. Concave Mirror:A concave mirror is a curved mirror with the reflecting surface on the hollow side (created by depositing silver metal on the outer curved side).
Convex Mirror : A convex mirror is a curved mirror

with the reflecting surface on the outerside.
Centre of Curvature : The centre of curvature of a curved mirror is defined as the center of the hollow glass sphere of which the curved mirror was (previously) a part.
Radius of curvature The radius of curvature of a curved mirror is defined as the radius of the hollow glass sphere of which the spherical mirror was (previously) a part. Note that any line drawn from the center of curvature C to the mirror surface meets it at right angle and equals the radius of curvature.
Principal Axis :The principal axis of a curved mirror is defined as the imaginary line passing through its pole P and center of curvature C.
Focus :The principal focus is defined as the point on the principal axis where the light rays traveling parallel to the principal axis after reflection actually meet (for a concave mirror) or appear to meet (for a convex mirror).
Pole : The pole is defined as the geometric center of the curved mirror. Rules of Reflection for Curved Mirrors
1. Any light ray traveling parallel to the principal axis is reflected by the curved mirror through the principal focus.
It either actually passes (for a concave mirror) or appears to pass (for a convex mirror) through the principal focus.
2. Any light ray that passes (for a concave mirror) or appears to pass (for a convex mirror) through the principal focus is reflected by the curved mirror parallel to the principal axis.
3. Any light ray that passes (for a concave mirror) or appears to pass
