Spectroscopy or spectrography both the terms referred to the measurement of radiation intensity and function of wavelength which are used to describe spectroscopic experimental methods. spectrometers, spectrophotometers, spectrographs or spectral analyzers are some of the devices. observation of color can be related to spectroscopy Neon lighting is a direct application of atomic spectroscopy and spectral characteristics generate specific colors and hues.
These Spectroscopic studies included Max Planck's explanation of blackbody radiation, Albert Einstein's explanation of the photoelectric effect and Niels Bohr's explanation of atomic structure and spectra which are used in developing the quantum mechanics. Spectroscopy is used in physical and analytical chemistry because atoms and molecules have unique spectra which is used to detect, identify and quantify. Spectroscopy is also used in astronomy and remote sensing. Telescopes have spectrographs which are used in determining the chemical composition and physical properties of astronomical objects.
Types of spectroscopy
Absorption spectroscopy, Emission spectroscopy, Elastic scattering and reflection spectroscopy, Crystallography, Impedance spectroscopy, Raman and Compton scattering, Coherent or resonance spectroscopy, Nuclear magnetic resonance (NMR) spectroscopy, Fourier-transform spectroscopy, Spectrophotometry which are more frequently used inn chemical analysis and chemistry labs.
