What is Spectroscopy

Since time immemorial, a concept that has continued to intrigue mankind is the science of light. Have you ever stopped to wonder how lights of different colours are formed? Have you ever thought about the nature and principles of light, its properties and the multifarious processes related to the concept of light? Then, Spectroscopy is an intriguing field you must study! It is a sub-discipline of science that studies the process of absorption and emission of light and radiations of differing wavelengths by different forms of matter. It is an interdisciplinary blend of principles of physics and chemistry. This blog aims to elaborate upon what is spectroscopy, courses offered in this field as well as career scope it entails. 


Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. In simple words, it is the study of colours as generalized from visible light to all the bands of the electromagnetic spectrum. Spectroscopic analysis is a fundamental concept that has been used in recent years to bring about revolutionary changes in the world of physics especially in areas of quantum mechanics. Now its presence can be felt in virtually all areas of technology from the medical research to the magnetic field. Studying spectroscopy, you will get to know about electromagnetic fields of both strong and weak nuclear forces. The principles of spectroscopy can be used to study the structure of elements and atoms and can be used to unravel the mysteries of electrons and protons.
