NEET Physics Lenses Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Focal length of convex lens | (i) Negative value |
| (b) Focal length of concave lens | (ii) Positive value |
| (c) Combination of two lenses | (iii) Effective focal length |
| (d) Power of a lens | (iv) Measured in diopters |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-i, d-iii
a-iv, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
A convex lens has a positive focal length, while a concave lens has a negative focal length. The combination of lenses leads to an effective focal length, and the power of a lens is measured in diopters, which is the reciprocal of the focal length in meters.
