Correct option is D
The correct option is: (d) at the centre of curvature, real, inverted and of the same size
Aconcave mirrorforms an image based on the object's position relative to itsprincipal focus (F)andcentre of curvature (C).
When the object is placedat the centre of curvature (C), the image is formedat the same point, i.e., atC.
The image isreal,inverted, andof the same sizeas the object due to symmetrical ray convergence.
Type of Mirror: Concave (converging mirror).
Ray Behavior: Parallel rays after reflection pass through the focus; rays through centre reflect back on themselves.
Image Nature: Real and inverted (can be projected on a screen).
Image Position: Formed exactly at the centre of curvature.
Magnification: Magnification (M) = -1 (same size but inverted).
Use Case: Commonly used in shaving mirrors and dentist’s mirrors when magnified reflection is needed (object closer than C).
Option (a): Incorrect; object at focus forms image at infinity, not diminished or virtual.
Option (b): Happens when the object is at focus (F), not at centre (C).
Option (c): Describes the condition when the object isbetween pole and focus, not at centre of curvature.
