0Two slits at a distance of \( 1 \mathrm{~mm} \) are illuminated by a light of wavelength \( 6.5 \times 10^{-7} \mathrm{~m} \). The interference fringes are observed on a screen placed at a distance of \( 1 \mathrm{~m} \). The distance between third dark fringe and fifth bright fringe will be
(A) \( 0.65 \mathrm{~mm} \)
(B) \( 3.25 \mathrm{~mm} \)
(C) \( 1.63 \mathrm{~mm} \)
(D) \( 4.88 \mathrm{~mm} \)
