NEET Physics Interference Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Constructive interference (i) S1P ~ S2P = (n + 1/2) λ (b) Destructive interference (ii) Resultant intensity = 4I0 (c) Coherent sources (iii) Phase constant (d) Incoherent sources (iv) Intensities add up
Choose the correct matching:
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iii, d-iv
Correct Answer
Detailed Explanation
Constructive interference occurs when the path difference equals nλ, resulting in maximum intensity (4I0), while destructive interference occurs at (n + 1/2) λ, leading to cancellation. Coherent sources maintain a fixed phase relationship, contrasting with incoherent sources where intensities simply add up without a fixed phase.
