Convex Mirror
Convex mirror is a spherical Curved mirror in which reflection takes place in the outer surface of the sphere of which the mirror is a part. Convex mirror has bulged outside at middle on the reflecting surface.It has also called fish eye. It has Painted on inner surface as shown in figure below:-
Convex mirror diverges the incomming rays of light when they strike the reflecting surface of the mirror. Hence, it has also known as the diverging mirror. Generally, image formed by convex mirror is virtual, errect and diminished in size. Both focus and centre of curvature in the case of convex mirror are imaginary points inside the mirror. Therefore, image formed by convex mirror cannot be projected on the screen.
Important Terms of Convex Mirror
[image uploded soon]
1)Pole
The center of spherical reflecting surface of the mirror has called the pole. It has denoted by P as shown in above given figure.
2)Centre of curvature
The centre of the sphere of which the mirror is a part has called the centre of curvature. It has denoted by C as shown in above given figure.
3)Radius of curvature
The radius of the sphere of which the mirror is a part has called the radius of curvature. It has denoted by R as shown in above given figure.
4)Principal Axis
A line which has drawn through the pole of the mirror and the centre of curvature has called principal axis. It has shown in the above given figure.
5)Principal Focus
In the case of convex mirror, principle focus is the point at which all parallel rays close to the principal axis appear to diverge from it after reflection. It has also called the focal point. It has denoted by F as shown in above given figure.
6)Focal plane
A plane which is perpendicular to the principal axis and passes through the focal point has called focal plane. It is the plane where rays of light parallel with each-others but not parallel with the principal axis appear to diverge from it after reflection. It has shown in above given figure.
7)Focal length
The distance between the pole of the mirror and its principal focus has called focal length. Focal length of convex mirror is negative. It is denoted by small f as shown in above given figure.
8)Aperture
The diameter of the boundary of the mirror is called aperture. XY is the aperture in above given figure.
