Where does the centre of curvature of a concave mirror lie?
In front of the mirror
The correct answer is option 4 i.e. In front of the mirror.
The centre of curvature of a concave mirror lies in front of the mirror. A concave mirror has an inward-curved surface, and the centre of curvature is the point on the optical axis that is at a distance equal to the radius of curvature from the mirror's surface. In this case, the focus and centre of curvature are located on the same side as the object. The reflection of light rays from a concave mirror forms a real image in front of the mirror, and the centre of curvature helps in understanding the mirror's focal length and image formation.
