Two slits are 0.168 mm apart. A mixture of red light (wavelength = 664 nm) and yellow-green light (wavelength = 568 nm) falls on the slits. A flat observation screen is located 2.41 m away. What is the distance on the screen between the third-order red fringe and the third-order yellow-green fringe?
