The virtual image can be formed by
(A) Plane mirrors
(B) Concave mirrors
(C) Convex mirrors
(D) Convex lens
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A), (B), (C) and (D)
A virtual image is formed where reflected or refracted rays only appear to meet. The question asks whether each device can form one under some position of the object.
(A) Plane mirrors — Correct. A plane mirror always forms a virtual, erect image of a real object.
(B) Concave mirrors — Correct. When the object is between the pole and the focus, the image is virtual, erect and magnified (a shaving mirror).
(C) Convex mirrors — Correct. A convex mirror always forms a virtual, erect, diminished image of a real object.
(D) Convex lens — Correct. When the object is between the optical centre and the focus, the image is virtual, erect and magnified (a simple magnifier).
