Studies of matter and to get structural parameters and properties of it has been a question in front of mankind since past. Several experiments and observations were made in this regard, Several laws and theories were given for this purpose. These studies can be broadly divided into studies based on classical mechanics and those based on quantum mechanics. Classical mechanics which is based on Newton's law of motion, was not able to explain the behaviour and concept of black body radiation. Due to inadequacy of classical mechanics, quantum mechanics was originated.
This mechanics is based on concept of quantization as explained by Max Planck, Need to study this mechanics is obvious if one has to get the first hand knowledge of structure and properties of material/matter.
