Answer :

a) Pole: Pole is the mid-point of the spherical mirror. It’s a point where the principal axis meets the mirror.

b) Centre of curvature: It is the center of the sphere of which the mirror is a small section.


c) Focus: When parallel rays are incident on the mirror, the reflected rays converge to or diverge from a point. This point is called the focus.


d) Radius of curvature: It is the radius of the sphere of which the mirror is a small section.


e) Focal length: Focal length is the distance between the pole & the principal focus. Also, its half the radius of curvature.


f) Principle axis: The principle axis is the line passing through the center of curvature and the pole. It extends infinitely on both sides.


g) Object distance: The distance of the object from the pole is called the object distance.


h) Image distance: The distance of the image from the pole is called the image distance.


i) Magnification: It is defined as the ratio of image height to the object height.


Alternatively, it is the ratio of image distance to the object distance.
