A diffraction grating has 5310 slits/cm. By illuminating it with light from an argon laser, a diffraction pattern is observed on a wall at a distance of l = 1.49 m. The distance between the central maximum and the first order maximum is 0.423 m. Determine the wavelength of the laser light used in the experiment and determine which color it corresponds to.
