Hi
Where does the image formed when the object is kept beyond the centre of curvature of the concave mirror?
Characteristics of the image When the object is placed beyond the centre of curvature of concave mirror:
When the object AB is placed beyond the centre of curvature then a ray of light AD which is parallel to the principal axis and another ray ARE which pass through the centre of curvature intersect each other after reflection at point A’ between the focus and centre of curvature. Thus the image formed is between the principal focus F and centre of curvature C, diminished, real and inverted.
