Question

A convex lens gives a virtual image when the object is placed on the principal axis

• A. at infinity
• B. at the centre of curvature
• C. beyond the centre of curvature
• D. between focal point and optic centre

Answer 1

The Correct Option is D

When an object is placed between the focal point (F) and the optic center (O) of a convex lens, the image formed is virtual, erect, and magnified. This occurs because the light rays after passing through the lens diverge, and when extended backward, they appear to converge at a point behind the lens, forming a virtual image. Thus, the virtual image is formed between the focal point and the optic center. Therefore, the correct answer is: between the focal point and optic centre.

The correct option is (D): between focal point and optic centre
