With the help of a ray diagram, determine the position, nature and size of the image formed of an object placed at the centre of curvature of a concave mirror.
When an object is placed at the centre of curvature $(C)$ of a concave mirror, the image formed will be:
(i) at the centre of curvature $(C)$,
(ii) real and inverted,
(iii) of the same size as the object.
Explanation
A concave mirror is a mirror that is curved inward in the middle. It is also known as converging mirrors, due to the fact that when parallel incident rays fall on the surface of the mirror, the rays will reflect and meet at a particular point and form the
image. Depending on the position of the object with respect to the mirror, the types of images it forms are real, inverted as well as virtual and erect image, also the size of the images formed are magnified, diminished as well as the same size as that of the object.
