The Planck's Distribution of Radiation describes the energy volume density radiated of a black body in terms of frequency or wavelenght. A black body is a material or a physical device that absorbs light and radiates it back not as usual reflected light but as the outcome of electrons reducing their energy levels. The formula is basically an interpolation of Wiens formula and some of plancks considerations on statistical physics. It casually introduces quantization of energy as a mathematical artiluge to fit results, but agrees with the actual understanding of photons as discrete particles. Hope this help you some bit ;-D
What else can I help you with?
Who discovered blackbody radiation?
Blackbody radiation was discovered by Max Planck in 1900. Planck proposed a theory that described the spectral distribution of energy emitted by a blackbody at different temperatures, leading to the development of quantum mechanics.
How did max planck called an object radiated energy?
Max Planck called an object radiating energy a "blackbody." He developed a theoretical model to explain the energy distribution of radiation emitted by a blackbody at different temperatures, leading to the development of quantum theory.
Does a blackbody emit all its radiation at a single frequency?
No, a blackbody emits radiation over a range of frequencies, not just a single frequency. The distribution of radiation emitted by a blackbody is described by Planck's law, which shows that the intensity of radiation varies with different wavelengths.
What did planck assume in order to explain the experimental data for blackbody radiation?
Max Planck assumed that the energy emitted by oscillators in a blackbody is quantized, meaning it can only take on discrete values, in order to explain the experimental data for blackbody radiation. This assumption led to the development of the famous Planck's law, which accurately described the spectrum of radiation emitted by a blackbody.
Who introduced the concept of quantam theory of radiation?
The concept of quantum theory of radiation was introduced by Max Planck in 1900. Planck's theory proposed that radiation is emitted and absorbed in discrete packets of energy, known as quanta. This laid the foundation for the development of quantum mechanics.

Who is the founder of quantum theory of radiation?
Max Planck
Who were the scientist who studied about radiation?
Many. Stefan, Kirchhoff, Wien, Prevost, Max Planck etc. Out of those Max Planck was the revolutionary one who introduced quantum concept on radiation.
How are energy and frequency of electromagnetic radiation related?
Energy = hf where h is Planck's Constant and f is the radiation frequency.

What is the frequency of Planck equation refers to?
The frequency in Planck's equation refers to the frequency of electromagnetic radiation, such as light. The equation relates the energy of a photon to its frequency through the constant known as Planck's constant.
What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
Describe the spectral distribution of energy in black body radiation?
The spectral distribution of energy in black body radiation is described by Planck's law, which shows that the intensity of radiation emitted by a black body as a function of wavelength is dependent on its temperature. As the temperature increases, the peak of the emitted radiation shifts to shorter wavelengths, a phenomenon known as Wien's displacement law. The distribution is continuous and features a characteristic curve that rises steeply at lower wavelengths, reaches a maximum, and then falls off at higher wavelengths. This distribution illustrates that black bodies emit a wide range of wavelengths, with the total energy emitted increasing with temperature, as described by the Stefan-Boltzmann law.
What is the true statement about Planck's law?
Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature.
