The interactions of radiations and matter are the subject of
spectroscopy or spectrochemical methods (also called
spectrometry).
Spectrochemical methods usually measure the
electromagnetic radiation produced (emitted) or absorbed
by molecular or atomic species of interest.
It has to be added though that spectroscopy nowadays
includes some methods that do not involve EM radiation,
such as acoustic and mass spectroscopy.
Introduction to
Spectrochemical Methods
11. Spectroscopic methods are among the most
selective and sensitive analytical methods,
and therefore are the second most widely
used methods (after chromatography).
Spectroscopy also played an important role
in the development of atomic theory.

Light consists of electromagnetic radiations EMR.
EMR travels in the form of a wave.
13.
Wave nature of Light
All EMR are associated with oscillating electric as
well as magnetic fields at right angle to each other
and also at right angle to direction of propagation.

Wavelength is the distance between two successive crests or
trough of a wave, especially points in a sound wave or
electromagnetic wave.

Frequency
The number of waves that pass a fixed point in unit time
or the Frequency of EM wave is the number of
oscillations that occur in one second.
