Question

At what position of a concave mirror do we get an image which is equal to the size of the object? What change will we observe in the size of the image if we move it further towards the mirror?

Answer 1

Answer:

At the center of curvature, the object distance equals the image distance and the object height equals the image height. As the object distance approaches one focal length, the image distance and image height approaches infinity. Finally, when the object distance is equal to exactly one focal length, there is no image.
