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