Match the LIST-I with LIST-II (Symbols have their usual meaning)
| LIST-I The nature of an image formed by a concave mirror. | LIST-II Position of Object |
| A. Inverted, real and magnified | I. Between P and F |
| B. Inverted, real and same size | II. Between C and infinity |
| C. Inverted, real and diminished | III. At C |
| D. Erect, virtual and magnified | IV. Between F and C |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A - IV, B - III, C - II, D - I
For a concave mirror, the nature and size of the image depend on where the object is placed relative to the focus F and the centre of curvature C (with PC = 2PF).
(A) Inverted, real and magnified — this matches (IV) Between F and C. The reflected rays meet beyond C, so the real, inverted image is farther from the mirror than the object and larger.
(B) Inverted, real and same size — this matches (III) At C. Rays from an object at C return to C, so the image forms at C with magnification −1.
(C) Inverted, real and diminished — this matches (II) Between C and infinity. The image forms between F and C, closer to the mirror than the object, so it is smaller.
(D) Erect, virtual and magnified — this matches (I) Between P and F. The reflected rays diverge, so they only appear to come from a point behind the mirror, giving an erect, enlarged virtual image; this is how a shaving mirror works.
