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) Random phase changes
Choose the correct matching:
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
a-ii, b-iii, c-iv, d-i
Correct Answer
Detailed Explanation
Constructive interference occurs when the path difference is an integer multiple of the wavelength, resulting in maximum intensity (4I0). In contrast, destructive interference occurs with a path difference of (n + 1/2)λ, leading to cancellation. Coherent sources maintain a fixed phase relationship, while incoherent sources exhibit random phase changes.
