NEET Physics Optical Instruments Assertion Reason Question
Assertion (A): The thin lens formula is applicable to both convex and concave lenses for real and virtual images. | Reason (R): The focal points of a double convex lens are equidistant from the optical center.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
While both statements are true, the reason does not explain why the thin lens formula is applicable to both convex and concave lenses. The formula's validity comes from the symmetry in lens geometry, not the equidistance of focal points.
