Unformatted text preview: the bright fringes? Since the condition for a bright fringe is d sin θ m = m λ , in order to decrease the fringe separation, you must move the screen closer to the slits or decrease − m-1 . To do the latter, you must either increase d or decrease . Submerging the apparatus in water has the effect of changing to /1.33, and thus it accomplishes this....
