Ideal Lamp for Photoelectric Effect Experiment
High-pressure Mercury lamp is a vapor or gaseous discharge lamp that uses Mercury in an excited state to produce light. Arc discharge takes place in a transparent tube inside a larger bulb of glass. The outer bulb reduces the ultraviolet radiation of the inner arc tube. Radiation from the Mercury arc is confined to four specific wavelengths in the visible range and several strong lines in the ultraviolet. This lamp is an ideal source for the photoelectric effect experiment, as well as many industrial and research applications that require ultraviolet radiation. LLE-9 is specially designed as a lab instrument.
