Answer:D
How can stability of radiation be achieved in incandescent or discharge source used in Absorption Spectroscopy?
A. Using filters B. Using monochromators C. Using slits D. By controlling the source voltage
Explanation: The intensity of radiation in incandescent source is proportional to the lamp source voltage. Therefore, by controlling the source voltage stability can be achieved.
