Chapter 9, Problem 9.5QAP

Interpretation Introduction

Interpretation:

The reason behind the use of source modulation in atomic absorption spectroscopy needs to 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 as compared to the frequencies nearby.

Monochromators are optical devices which transmit from a wide range of available wavelengths, a mechanically selectable narrow wavelength band. These could be wavelengths of light or any other radiation.
