Question

A concave lens always forms the same type of image for any position of the object. State the nature of this image in terms of: (i) real or virtual, (ii) erect or inverted, and (iii) enlarged or diminished.

Accepted Answer

## Model Answer A concave lens always forms an image that is (i) **virtual**, (ii) **erect**, and (iii) **diminished**, irrespective of the position of the object. Source: Light – Reflection and Refraction, Table 9.5 ## Explanation The textbook explicitly states: *"A concave lens will always give a virtual, erect and diminished image, irrespective of the position of the object."* (Table 9.5). Examiners expect all three terms — virtual, erect, diminished — for full marks. Missing even one term may cost the mark.
