I don’t seem to get Planck’s postulates on quantum physics. (Posted Isaac Atia)

The Planck postulate (or Planck’s postulate) is one of the fundamental principles of quantum mechanics. According to Planck, the energy of oscillators in a black body is quantized, and is given by

# E = n hν

where is an integer (1, 2, 3, …), is Planck’s constant, and * is the frequency of the oscillator*
