Quizplus · Accepted Answer

The best choice for the light source in an atomic absorption spectrophotometer is a hollow cathode tube. This is because it produces a narrow and intense line of radiation that corresponds to the element being analyzed, making it the ideal light source for atomic absorption spectroscopy. Prisms and tungsten lights are not suitable as they do not produce the necessary narrow and intense line of radiation, while laser light is not commonly used as a light source in atomic absorption spectrophotometers.
