MCQ
In a $YDSE$, the central bright fringe can be identified :
  • A
    as it has greater intensity than the other bright fringes.
  • B
    as it is wider than the other bright fringes.
  • C
    as it is narrower than the other bright fringes.
  • ✓
    by using white light instead of single wavelength light.
✓

Answer

Correct option: D.
by using white light instead of single wavelength light.
d
Using white light will the central maxima because in this case central maxima is completely white and all other maximas are colorful.

Therefore, Option $D$ is correct answer.
