Question

From which lens the image of object formed is virtual, erect and smaller than the object?

• A. Concave lens
• B. Convex lens
• C. Plane lens
• D. None of these

Hint:

A concave lens always forms a virtual, erect, and diminished image irrespective of the object position.

Answer 1

The Correct Option is A

Step 1: Understanding the property of lenses.
A concave lens diverges light rays that pass through it. The image formed by a concave lens is always virtual, erect, and smaller than the object.
Step 2: Analyzing the options.
(A) Concave lens: Correct — forms a virtual, erect, and diminished image.
(B) Convex lens: Incorrect — usually forms a real and inverted image, except when the object is between the focus and lens.
(C) Plane lens: Incorrect — produces an image of the same size and orientation as the object.
(D) None of these: Incorrect — since the correct lens is concave.
Step 3: Conclusion.
Therefore, the lens that forms a virtual, erect, and smaller image is the concave lens.
