In a double-slit experiment, the third-order maximum for light of wavelength 490 nm is located 15 mm from the central bright spot on a screen 1.6 m from the slits. light of wavelength 670 nm is then projected through the same slits. how far from the central bright spot will the second-order maximum of this light be located?
