Question 10 of 12 - /1 . . . View Policies Current Attempt in Progress A slit has a width of W1 = 4.4 x 10 m. When light with a wavelength of 11 = 699 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 12 = 476 nm is used. The width of the central bright fringe on the screen is observed to be unchanged. Find W2. W2=
