How does black body radiation explain particle nature of electromagnetic radiation Furthermore how does the EM wave theory fail to explain this phenomenon 7 and arrived at a satisfactory relationship by making an assumption that absorption and emmission of radiation arises from oscillator i e atoms in the wall of black body Their frequency of oscillation is changed by interaction with oscilators of electromagnetic radiation Planck assumed that radiation could be sub divided into discrete chunks of energy He suggested that atoms and molecules could emit or absorb energy only in discrete quantities and not in a continuous manner He gave the name quantum to the smallest quantity of energy that can be emitted or absorbed in the form of electromagnetic radiation The energy E of a quantum of radiation is proportional experim to its frequency v and is expressed by orily on equation 2 6 2 6 Max Pla E hv The proportionality constant h is known as Planck s constant and has the value 6 626x10 34 J s With this theory Planck was able to explain the distribution of intensity in the radiation from black body as a function of frequency or wavelength at different temperatures ed intens in any its its tempera sity of radi he increas um value arts decrea as sh ngth ture increa rt wavelen o predict function Quantisation has been compared to standing on a staircase A person can stand on any step of a staircase but it is not possible for him her to stand in between the two steps The energy can take any one of the values from the following set but cannot take on any values between them E 0 h 2h 3hn nhu Uni Priz Pla the Pho In 1 exp cur exa wel in Ph thi i
