NEET Physics Interference Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Constructive interference | (i) Resultant intensity 4I_0 |
| (b) Destructive interference | (ii) Resultant intensity 0 |
| (c) Coherent sources | (iii) Fixed phase relationship |
| (d) Incoherent sources | (iv) Rapid phase changes |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
Constructive interference occurs when the path difference results in a phase difference of 0, leading to a resultant intensity of 4I_0. Destructive interference happens when the phase difference is π, resulting in zero intensity. Coherent sources maintain a fixed phase relationship, while incoherent sources exhibit rapid phase changes, preventing consistent interference patterns.
