A slit has a width of W1 = 5.0 x 10-6 m. When light with a wavelength of ?1 = 722 nm passes through this slit, the width of the central bright fringe on a flat observation screen has a certain value. With the screen kept in the same place, this slit is replaced with a second slit (width W2), and a wavelength of ?2 = 530 nm is used. The width of the central bright fringe on the screen is observed to be unchanged. Find W2.
