The spectrum of light from heated up hydrogen gas has only a few wavelengths present. These are known as spectral lines. It includes a red line at 656 nm and a blue-violet line at 434 nm. What are the angular separations between these two spectral lines for all visible orders obtained with a diffraction grating that has 4770 grooves/cm? (In this problem assume that the light is incident normally on the grating.) I'm having trouble with this question as I'm...
