In a "concave mirror", when the position of the object is at the Centre of Curvature (C), what will be the position of the image?

At C ( Center of Curvature )

Beyond C ( Center of Curvature )

At Infinity

Behind the mirror

✅ Correct Option: 1

For a concave mirror with the object at the centre of curvature, $u = -2f$ , and the mirror formula gives $v = -2f$ as well.

The image forms at C itself and is real, inverted and the same size as the object.
