| Column-I | Column-II |
|---|---|
| (a) Focal length of a convex lens | (i) Positive |
| (b) Focal length of a concave lens | (ii) Negative |
| (c) Power of a convex lens | (iii) Positive |
| (d) Power of a concave lens | (iv) Negative |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
Convex lenses have a positive focal length and power, while concave lenses have negative values for both. This aligns with the definitions provided in the NCERT context regarding focal lengths and powers of different lenses.
