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
Choose the correct matching:
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.
