NEET Physics (general) 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) Plane polarised wave | (i) Random displacement |
| (b) Critical angle | (ii) n1 sin i = n2 sin r |
| (c) Unpolarised wave | (iii) Displacement at right angles |
| (d) Refraction in denser medium | (iv) Decreased wavelength and speed |
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-iv, c-iii, d-i
C
a-i, b-iv, c-ii, d-iii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
A plane polarised wave has displacement at right angles to the direction of propagation (a-iii). The critical angle is defined by n1 sin i = n2 sin r (b-ii). An unpolarised wave has random displacement (c-i). In a denser medium, the wavelength and speed decrease (d-iv).
