Q. In an interference experiment, phase difference for points where the intensity is minimum is $(n = 1,\ 2,\ 3,\ \ldots.)$
A) $n\pi$
B) $(n + 1)\pi$
C) $(2n - 1)\pi$
D) Zero
Explanation
(c) The intensity I is minimum for phase difference,
$\ \ \ \delta = (2n - 1)\pi$
Where $\ n = 1,\ 2,\ 3,\ \ldots\ldots$
