WebDec 3, 2010 · Assumptions used: 1. The particles/oscillators near the surface of the blackbody which emits the blackbody radiation can only have discrete values of energy, E n: E n =nhf, where n is a positive interger, f is the frequency of the oscillating particle, h is the Planck’s constant. Particles can only have discrete values of energy. WebJSTOR Home
WebToday we discuss the beginnings of the so-called Quantum Theory. This began with Planck's formula for explaining the continuous spectrum of light radiation from heated solids. He found it was necessary to postulate that the energies associated with oscillating electrons in atoms had to have certain discrete values, i.e., the energies were ...
WebMay 8, 2005 · Here is Planck's rule for the a quantum of energy for a vibrating electron: energy of a quantum = (a calibration constant) x (frequency of vibration) or. E = hf. where h, the calibration constant, is today called Planck's constant. Its value is about 6 x 10-34, very tiny! So how does this explain the spectrum of blackbody radiation? dマーケット 解約 電話WebJul 31, 2024 · The relation is E = hυ, Where E is energy of photon, h is Planck’s constant and υ is the frequency of the radiation.
