At equilibrium, the radiation inside this enclosure follows Planck's law, and so will the radiation coming out of the small hole. Just as the Maxwell—Boltzmann distribution is the unique maximum entropy energy distribution for a gas of material particles at thermal equilibrium, so is Planck's distribution for a gas of photons.

If the photon gas is not Planckian, the second law of thermodynamics guarantees that interactions between photons and other particles or even, at sufficiently high temperatures, between the photons themselves will cause the photon energy distribution to change and approach the Planck distribution.

In such an planck s quantum theory to thermodynamic equilibrium, photons are created or annihilated in the right numbers and with the right energies to fill the cavity with a Planck s quantum theory distribution until they reach the equilibrium temperature.

What is quantum theory? - Definition from

It is as if the gas is a mixture of sub-gases, one for every band of wavelengths, and each sub-gas eventually attains the common temperature. At the time he proposed his radical hypothesis, Planck could not explain why energies should be quantized.


Initially, his hypothesis explained only one set of experimental data—blackbody radiation. If quantization were observed for a large planck s quantum theory of different phenomena, then quantization would become a law.

In time, a theory might be developed to explain that law. Max Planck explain the spectral distribution of blackbody radiation as result from oscillations of electrons. Similarly, oscillations of electrons in an antenna produce radio waves.

Planck's law - Wikipedia

Max Planck concentrated on modeling the oscillating charges that must exist in the oven walls, radiating heat inwards and—in thermodynamic equilibrium—themselves being driven by the radiation field.

With that planck s quantum theory, Planck calculated the following formula for the planck s quantum theory energy density inside the oven: Since we do not know, the cat is both dead and alive, according planck s quantum theory quantum law - in a superposition of states.

It is only when we break open the box and see what condition the cat is that the superposition is lost, and the cat must be either alive or dead. The second interpretation of quantum theory is the many-worlds or multiverse theory. It holds that as soon as a potential exists for any object to be in any state, the universe of that object transmutes into a series of parallel universes equal to the number of possible states in which that the object can exist, with each universe containing a unique single possible state of that object.

Furthermore, there is a mechanism for interaction between these universes that somehow permits all states to be accessible in some way and for all possible states to be affected in some manner. Stephen Hawking and the late Richard Feynman are among the scientists who have expressed a preference for the many-worlds theory.

Quantum Theory's Influence Although scientists throughout the past century have balked at the implications of quantum theory - Planck and Einstein among them planck s quantum theory the theory's principles have repeatedly been supported by experimentation, planck s quantum theory when the scientists were trying to disprove them.

Quantum theory and Einstein's theory of relativity form the basis for modern physics.

What is Planck's quantum theory about? - Quora

The principles of quantum physics are being applied in an increasing number of areas, including quantum optics, quantum chemistry, quantum computingand quantum cryptography.

This revolutionary idea stemmed from blackbody radiation.


A blackbody is an object that absorbs all the radiation falling on it. An object that absorbs all the radiation can also perfectly emit all radiation therefore a blackbody will radiate maximum energy when heated to a given temperature.

Under classical physics this energy emitted was predicted to be planck s quantum theory.
