Interference fringes are produced on a screen at a distance of 1.50 m from two slits having separation of \( 0.6 \times 10^{-3} \) . If the width of interference fringe is \( 1.5 \times 10^{-3} \) , determine the wavelength of light.

A 4000 \( \text{\AA} \)

B 5000 \( \text{\AA} \)

C 6000 \( \text{\AA} \)
