Light waves with two different wavelengths, 632 nm and 474 nm,pass simultaneously through a single slit whose width is 7.15× 10-5 m and strike a screen 1.20 m from the slit.Two diffraction patterns are formed on the screen. What is thedistance (in cm) between the common center of the diffractionpatterns and the first occurrence of a dark fringe from one patternfalling on top of a dark fringe from the other pattern?
