Question

Given below are two statements:
Statement (I): When an object is placed at the centre of curvature of a concave lens, image is formed at the centre of curvature of the lens on the other side.
Statement (II): Concave lens always forms a virtual and erect image.
In the light of the above statements, choose the correct answer from the options given below:

• A. Statement I is false but Statement II is true.
• B. Both Statement I and Statement II are false.
• C. Statement I is true but Statement II is false.
• D. Both Statement I and Statement II are true.

Answer 1

The Correct Option is A

Statement I: A concave lens diverges light and does not have a centre of curvature for image formation in the context of lens theory. The centre of curvature is a concept applicable to mirrors, not lenses. Hence, Statement I is false.

Statement II: A concave lens always forms a virtual, erect, and diminished image irrespective of the position of the object. This is a fundamental property of concave lenses. Hence, Statement II is true.
Final Answer: (1) Statement I is false but Statement II is true.
