By attaching a diffraction-grating spectroscope to the astronomical telescope, one can measure the spectral lines from a star and determine the star's chemical composition. Assume the grating has 3230 lines/cm. (a) If the wavelengths of the star's light are 478.5 nm, 647.4 nm, and 696.4 nm, what are the angles at which the first-order spectral lines occur
