The reason for an emission line of the hollow-cathode lamp for molybdenum to develop a cuplike crater at its maximum at higher current needs to be explained. Concept introduction: Spectral lines are lines which help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby. Until the lamp current is less than 50 mA for a hollow cathode lamp for molybdenum, the emission spectrum is a sharp line at 313.3 nm.
