Assertion :- In YDSE, as shown in figure, central bright fringe is formed at \( \mathrm{O} \). If path difference at \( \mathrm{O} \) increases y-coordinate of central bright fringe will change.
Reason :- In YDSE, as shown in figure, central bright fringe is formed at \( \mathrm{O} \). If a liquid is filled between plane of slits and screen, the central bright fringe is shifted in upward direction.
