NEET Physics Lenses Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
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
Choose the correct matching:
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-i, d-iii
D
a-iv, b-ii, c-iii, d-i
Correct Answer
Option A
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.
