How to solve this problem?

  1. Dec 8, 2005 #1
    Two slits are 0.158 mm apart. A mixture of red light wavelength = 665 nm and yellow green light wavelength = 565 nm falls on the slits. A flat observation screen is located 2.24 m away What's the distance on the screen between the third order red fringe and the third order yellow green fringe?

    Thanks
