Adiffraction grating with 1000 lines per mm is used in a spectrometer to measure the wavelengths of light emitted from a gas discharge tube. you measure the diffraction angle to be at 20° for one emission line. what would happen to this emission line’s diffraction angle if you replaced the diffraction grating with one having 500 lines per mm instead
