1) The emission spectrum of a hollow cathode lamp for molybdenumwas found to have a sharp peak at 313.3 nm as long as the lampcurrent was less than 50 mA. At higher currents, however, the peakdeveloped a cup-like crater at its maximum. Explain. 2) Why doesthe cathode of the hollow cathode lamp have a cylindrical shape?Why is an element lamp required as the source for AA? Which copperline was used for analysis of copper in the CAM experiment?
