pole: the midpoint (geometrical centre) of spherical mirror is known as pole
Centre of curvature: all normals of rays converge at a point.that is known as centre of curvature
Focus:the rays coming from the light parallel to the principle axis of concave mirror converge at a point this is called focus
Radius of curvature: the line passing through centre of curvature and pole is known as radius of curvature
Focal length: the distance between focus and pole is known as focal length
principal axis:the horizontal line passing through centre of curvature is known as principal axis
object distance:the distance between object and mirror is known as object distance
image distance: the distance between image and mirror is known as image distance
magnification:the relation between size of object and size of image
7) we can refer the real image or virtual image. And we can know the size of object and image. where the image is formed also
