Collimated red light (656.281 6 nm) from a hydrogen discharge lamp falls perpendicularly onto a transmission grating. The beam emerges forming a red line in the second-order spectrum at an angle of 42.00º with the central axis. Compute the number of lines per centimeter the grating must have. Determine the angular location of the blue (486.132 7 nm) line in the second-order hydrogen spectrum.
