A laser beam, with a wavelength of 532 nm, is directed exactly perpendicular to a screen having two narrow slits spaced 0.15 mm apart. Interference fringes, including a central maximum, are observed on a screen 1.0 m away. The direction of the beam is then slowly rotated around an axis parallel to the slits to an angle of 1.0°. By what distance does the central maxi- mum on the screen move?
