Q.2. (a) An atomic absorption spectrometer requires a very different light source than does an instrument for molecular absorption. Describe the light source used by each instrument and explain why these two instruments need such different light sources. As part of your answer, explain the consequences if you interchange the two types of sources.
(b) IR Spectroscopy has various sources for producing IR spectrum but we cannot use these in X-ray and Mass Spectroscopy, give an explanation.
