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) Identical phase relationship |
| (d) Path difference condition | (iv) Resultant amplitude = 2a |
a-ii, b-i, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
a-ii, b-iv, c-iii, d-i
a-iii, b-i, c-ii, d-iv
Correct Answer
Detailed Explanation
Constructive interference occurs when the path difference is an integer multiple of the wavelength, leading to a resultant intensity of 4I₀ as stated in the NCERT context. Destructive interference happens with a path difference of (n + 1/2)λ, resulting in cancellation of waves. Coherent sources maintain an identical phase relationship, which is essential for producing clear interference patterns.
