Want this question answered?
the centre of sphere is known as centre of curvature
the center of curvature is the ORIGIN of the radius of curvature
Because a ray that passes through the center of curvature falls perpendicular to the surface (along a normal to the surface), hence it is reflected along the same path.
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
Centripetal acceleration is acceleration towards the center of the movement.

If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
Centripetal acceleration is acceleration towards the center of the movement.
It is the distance, from any point on a curve, to the centre of curvature at that point.
PRINCIPAL AXIS
Radially, away from the centre of curvature at the point.
It is the center of the imaginary sphere to which the mirror belongs.
In mathematics, the radius of an arc is a straight line from the centre of curvature of the arc to the arc. In the case of a circle it is the line from the circle's centre to its circumference.
