NEET Physics Interference Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Constructive interference | (i) Path difference = (n + 1/2)λ |
| (b) Destructive interference | (ii) Resultant intensity = 4I₀ |
| (c) Coherent sources | (iii) Fixed phase relationship |
| (d) Incoherent sources | (iv) Rapid phase changes |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-iii, b-ii, c-i, d-iv
a-ii, b-iv, c-iii, d-i
Correct Answer
Detailed Explanation
Constructive interference occurs when the path difference is a multiple of the wavelength (resulting in maximum intensity), while destructive interference occurs when the path difference is a half-multiple of the wavelength (resulting in minimum intensity). Coherent sources maintain a fixed phase relationship, unlike incoherent sources which have rapid phase changes.
