Answer:
pole:-The point where the principal axis pierces the mirror is called the pole of the mirror.
Explanation:
center of curvature:-The point in the center of the sphere from which the mirror was sliced is known as the center of curvature and is denoted by the letter C
focus:-In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge. ... For a lens, or a spherical or parabolic mirror, it is a point onto which collimated light parallel to the axis is focused.
Radius of curvature:- the length between the center of curvature and the pole is known as radius of curvature.
focal Length:- The focal length ( f ) is the distance from a lens or mirror to the focal point ( F ). This is the distance from a lens or mirror at which parallel light rays will meet.
Principal Axis:- a line passing through the center of the surface of a lens or spherical mirror and through the centers of curvature of all segments of the lens or mirror.
object distance:- the distance between the pole and the object is known as the object distance.
image distance:- the distance between the image and the pole is known as image distance. If the image is in front of the mirror it will be negative but if it us behind the mirror it will be positive.
Magnification:- Magnification is also equal to the ratio of image distance to the object distance.
