NEET Physics Lenses Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Convex lens | (i) Negative focal length |
| (b) Concave lens | (ii) Positive focal length |
| (c) Effective power | (iii) Sum of individual powers |
| (d) Focal length | (iv) Radius of curvature |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-ii, b-iv, c-i, d-iii
Correct Answer
Detailed Explanation
A convex lens has a positive focal length, while a concave lens has a negative focal length. The effective power of a combination of lenses is the sum of their individual powers. The focal length is related to the radius of curvature, as stated in the context provided.
