NEET Physics Interference Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Bright fringe condition | (i) S1P ~ S2P = (n + 1/2)λ |
| (b) Destructive interference | (ii) Resultant intensity = 4I0 |
| (c) Path difference for bright fringe | (iii) xd = nλ |
| (d) Coherent sources requirement | (iv) Waves maintain a constant phase relationship |
a-ii, b-i, c-iii, d-iv
a-ii, b-iv, c-i, d-iii
a-iii, b-ii, c-i, d-iv
a-ii, b-iii, c-iv, d-i
Correct Answer
Detailed Explanation
The bright fringe condition occurs when the path difference is a multiple of the wavelength (xd = nλ), leading to maximum intensity (I = 4I0). Destructive interference occurs when the path difference is an odd multiple of half the wavelength (S1P ~ S2P = (n + 1/2)λ). Coherent sources must maintain a constant phase relationship to create a stable interference pattern.
