Q: Most widely used for producing IR source radiation-
  • A. Mercury lamp
  • B. Sodium lamp
  • C. Globar
  • D. Deuterium lamp
Correct Answer: Option C - For Infrared Spectroscopy a globar is employed as a thermal light source. It's a silicon carbide rod with a diameter of 5 to 10 mm and a length as 20 to 50 mm that has been electrically heated to 1000 to 1650°C.
