Which of the following analytical technique is based on the emission of light radiation?
Correct answer: A. Flame photometry
- A. Flame photometry
- B. Atomic absorption spectrophotometry
- C. Raman spectroscopy
- D. Conductometry
Explanation
In flame photometry, a sample is introduced into a flame, causing atoms to become electronically excited. As they return to their ground state, they emit light at characteristic wavelengths, and the intensity of this emission is measured.
