Detailed explanation-1: -Answer. Answer: it depends upon the distance of the object placed on the principal axis from the concave mirror.
Detailed explanation-2: -The size of the image depends upon the distance of the object from the mirror and it’s position with respect to the mirror’s surface.
Detailed explanation-3: -A concave mirror forms a real image equal in size to the object when the object is placed at the centre of curvature.
Detailed explanation-4: -EXPLANATION: If the object is at infinity, then the image obtained after reflection from a concave mirror is at the focus, highly diminished, real and inverted.
Detailed explanation-5: -Two rays emerge from the object, one of which is parallel to the principal axis, and the other moves towards the centre of curvature of the mirror. After reflection, the image is formed between the centre of curvature C and the focus F. The image formed is diminished, inverted, and real.
