Question

State the various assumptions made by planck

Answer 1

Planck assumed that the sources of radiation are atoms in a state of oscillation and that the vibrational energy of each oscillator may have any of a series of discrete values but never any value between. 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 = hν.
