Question
Chapter 9, Problem 9.8QAP
Interpretation Introduction
Interpretation:
The three things to increase the sensitivity of the nitrous oxide-acetylene burner needs to be explained.
Concept introduction:
Spectral lines help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby.
