Light at two different wavelengths, 750nm and 450nm, is shone through the same single slit at the same time. The two diffraction patterns are lined up to have a common central bright fringe, which appears on the screen 1.50m from the slit. The shortest distance from the centre of where dark fringes from each pattern overlap is 6.75cm. Determine the slit's width.
