Deriving Planck

WebPlanck figured out that energy was quantised when trying to explain black body radiation. At the time, the classical theory predicted that a body would radiate an infinite amount of power, which is obviously wrong. Planck found that by assuming the mode excitations were quantized he got a convergent answer. WebThe Planck constant (h) appears in many physics equations, most notably E=hf (otherwise known as the Planck relation or Planck-Einstein relation). Named after Max Planck, it is used to calculate the energy of the electromagnetic wave such as radio, light, microwaves, X …
