What aspect of the blackbody spectrum forced Planck to propose quantization of energy levels in its atoms and molecules?
A body that absorbs all the radiations falling on it, and reflects and transmits none is called black body and the electromagnetic radiations which are emitted by a black body are called black body radiations.
The emission of electromagnetic radiations for an object to emissivity of 1 Planck is recognize that the energy levels of the emitting atoms and molecules were quantized, this is first aspect that energy levels are quantized from blackbody radiations, with only the allowed values of
Here n, h respectively, any non-negative integer ( 0,1,2,3,.....) and Planck’s constant whose value is 6.626 x
Thus, an oscillator having frequency f can have its energy changes only in discrete steps of size given below.
Here, frequency of oscillatory nature of the absorption and emission of electromagnetic radiations is denoted by f and h is plank’s constant.
