Two of the lines of the atomic hydrogen spectrum have wavelengths of 656 nm and 410 nm.

Question:

Two of the lines of the atomic hydrogen spectrum have wavelengths of 656 nm and 410 nm. If these fall at normal incidence on a grating with 7700 slits / cm, what will be the angular separation of the two wavelengths in the first-order spectrum?
