Question
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.
Solution
When an object is placed at the centre of curvature of a concave mirror, the image formed will be as shown:
The image of an object placed at the centre of curvature of a concave mirror is real, inverted and of the same size as the object.
