6. An entire Young’s double s_l_i_t experiment is performed under water using light from a Nd- YAG laser λ = 1064 nm. Fringes are measured carefully on a screen 1.50 m away from the double s_l_i_t and the 3rd dark fringe is found to be 3 mm from the centre of the central bright fringe. Determine the location of the central bright fringe if a small piece of glass with thickness of 1.6μm is inserted over one of the s_l_i_t_s. The index of refraction of the glass is n = 2.66 and is n=1.33 for the water
