Light waves with two different wavelengths, 632nm and 474nm, pass simultaneously during a single slit whose width is 7.5 x10-5m and strike a screen 1.20 m from the slit. Two diffraction patterns are formed on the screen. What is the distance (in cm) between the common center of the diffraction patterns and the first occurrence of a dark fringe from one pattern falling on top of a dark fringe from the other pattern?
