A light source shines light consisting of two wavelengths, ?₁ = 540 nm (green) and ?₂ = 450 nm (blue), on two slits separated by 0.170 mm. The two overlapping interference patterns, one from each wavelength, are observed on a screen 1.31 m from the slits. What is the minimum distance (in cm) from the center of the screen to a point where a bright fringe of the green light coincides with a bright fringe of the blue light?
