Q.
Interference fringes are being produced on screen $XY$ by the slits$S_{1}\ and\ S_{2}$. In figure, the correct fringe locus is
A) $PQ$
B) $W_{1}W_{2}$
C) $W_{3}W_{4}$
D) $XY$
Explanation
(c) Interference fringes are bands on screen $XY$ running parallel to the length of slits. Therefore, the locus of fringes is represented correctly by$W_{3}W_{4}$.
