Young's double slit experiment is one of the quintessential experiments in physics. The availability of low cost lasers in recent years allows us to perform the double slit experiment rather easily in class. Your professor shines a green laser (562 nm) on a double slit with a separation of 0.111 mm. The diffraction pattern shines on the classroom wall 3.0 m away. Calculate the fringe separation between the fifth order and central fringe.
