Statement I: Two coherent point sources of light having no-zero phase difference are separated by a small distance. Then, on the perpendicular bisector of line segment joining both the point sources, constructive inteference cannot be obtained.
Statement II: For two waves from coherent point sources to interfere constructively at a point, the magnitude of their phase difference at that point must be `2 m pi` (where m is non-negative integer).

Options

A. Statement I is True, statement II is True, Statement II is a correct explanation for Statement I.
B. Statement I is Ture, Statement II is Ture, Statement II is NOT a correct explanation for Statement I.
C. Statement I is True, Statement II is False.
D. Statement I is False, Statement II is True.

Answer

d

Explanation

Statement I is false because constructive interference can be obtained if phase difference of sources is `2 pi, 4 pi , 6 pi`, etc.
