The phase difference between two wave trains giving rise to a dark fringe in Young's double slit interference experiment is (

\mathrm{n}

integer):

View answer and explanation

Correct option: B

2 \pi \mathrm{n}+\pi

Option B (

2 \pi \mathrm{n}+\pi

) is correct because a dark fringe (destructive interference) occurs when the phase difference is an odd multiple of

\pi

.
