NEET Physics Interference Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Constructive interference | (i) S1P ~ S2P = (n + 1/2) λ |
| (b) Destructive interference | (ii) Resultant intensity = 4I0 |
| (c) Coherent sources | (iii) Phase constant |
| (d) Incoherent sources | (iv) Intensities add up |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iii, d-iv
Correct Answer
Detailed Explanation
Constructive interference occurs when the path difference equals nλ, resulting in maximum intensity (4I0), while destructive interference occurs at (n + 1/2) λ, leading to cancellation. Coherent sources maintain a fixed phase relationship, contrasting with incoherent sources where intensities simply add up without a fixed phase.
