The reason for lower intensity of atomic line for Li in a natural gas flame, 1800 o C in comparison to the hydrogen-oxygen flame, 2700 o C should be determined. Concept introduction: Spectral lines are lines which 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. With the increase in temperature, there are more atoms excited and more electron transition happens from ground state to excited state. This results in more intensity of the emission line.

Interpretation Introduction

Interpretation:

The reason for lower intensity of atomic line for Li in a natural gas flame, 1800 oC in comparison to the hydrogen-oxygen flame, 2700 oC should be determined.

Concept introduction:

Spectral lines are lines which 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.

With the increase in temperature, there are more atoms excited and more electron transition happens from ground state to excited state. This results in more intensity of the emission line.
