Interpretation Introduction
Interpretation:
The reason for nonlinear relationship between absorbance and concentration of U should be explained.
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.
