Monochromatic light is incident on two identical and parallel slits of Young's double-slit setup. The slits are 3 mm apart, and the interference fringes are seen a screen 1.1 m away. If the bright fringes are separated by 3.9 mm, then find the phase difference (in rad) corresponding to the 8th bright fringe. 21.9911 O 40.8407 O 3.1416 O 18.8496 O 50.2655 O
