2 0 obj Near thermodynamic equilibrium, the emitted radiation is closely described by Planck's law and because of its dependence on temperature, Planck radiation is said to be thermal radiation, such that the higher the temperature of a body the more radiation it emits at every wavelength. Actually, the Planck-Einstein relationship (1) can even be derived on purely relativistic grounds, with the only additional assumption of the existence of an energy quantum, but without the need of postulating the speciﬁc value ~ω.

P1The state of a physical system is described by … A laser emits light energy in short pulses with frequency 4.69 × 1014 Hz and deposits 1.3 × 10–2 J for each pulse. Planck further assumed that when an oscillator changes from a state of energy E1 to a state of lower energy E2, the discrete amount of energy E1 − E2, or quantum of radiation, is equal to the product of the frequency of the radiation, symbolized by the Greek letter ν and a constant h, now called Planck’s constant, that he determined from blackbody radiation data; i.e., E1 − E2 = h ν. through its spatial location and time dependence, i.e. 2.

On the basis of these studies, Planck postulated a theory known as Planck’s quantum theory of radiations. The electron density in the area between the two bonding atoms increases as a result of this overlapping, thereby increasing the stability of the resulting molecule. The goal of this section is to introduce such principles, to-gether with some mathematical concepts that are necessary for that purpose. endobj >> The Planck postulate (or Planck's postulate), one of the fundamental principles of quantum mechanics, is the postulate that the energy of oscillators in a black body is quantized, and is given by =, where is an integer (1, 2, 3, ...), is Planck's constant, and (the Greek letter nu, not the Latin letter v) is the frequency of the oscillator..
