Light of a single wavelength is incident upon a diffraction grating that is 129 mm wide with 60,000 slits. The third order maximum (m3) has an angular position of 55° on the viewing screen placed 2.0 m away from the diffraction grating. What is the wavelength of the light (in units of nm) that is incident upon the diffraction grating? Please enter only the numerical value to the nearest whole integer, i.e., X, and do not include units.
