Answer 1

‌$\huge\mathcal{\boxed{\underline{\color{red}AnSwEr}}}$

Object at centre of curvature, C1 or 2F1:

A same sized, real and inverted image is formed at centre of curvature, C2 when object is placed at centre of curvature, C1 of a convex lens. Properties of Image: Image is same size as object, real and inverted.

‌$\huge\mathcal{\boxed{\underline{\color{red}OR}}}$

The characteristics of the image formed by the concave mirror for the object placed at the center of curvature is:

Position: At the center of curvature at the same side

Size: same as the size of the object

Nature: Real, inverted.
