The black body – a new point of view

In my previous post, “Etherons: quantum physic dismantled”, I have  proved something new.

Reintroducing an old concept

Reintroducing an abandoned concept, the  ether, all phenomena involving light become perfectly explainable from  an exclusively classical point of view. This way, it becomes very easy to describe all the electromagnetic radiations. And, in particular, the nature of light as a wave, with all its power to put in vibration the etherons. These invisible particles remain at their place, they  don’t move, but only oscillate, transmitting the wave in all directions.

All the light phenomena become, this way, perfectly explainable by the only aid of classical physics. Light loses its ambiguity, that is its double nature of particle and wave. It simply becomes a wave that propagates in particles.

In this article I will consider two more points, the black body radiation and the De Broglie consideration about matter being a wave. This is the inverse of what I have considered till now.

Quantization and Classical Physics

Many people think that quantum physics exists because it describes the discrete nature of radiations, the quantization. Moreover, they think it measures quantities in discrete, not continuous units. That’s true, this is one of the major ideas of quantum physics. Anyway, this is not so peculiar. It is not this what  makes the quantum physics one of the scientific branches you cannot do without. Classic physics can describe discrete quantities too. The double nature of light and matter is the only point actually making it impossible for classical physics  a plane description of electromagnetism.

The idea of quantized energies came to the fore when considering one big point: the black body radiation. Let’s try to describe this problem that has challenged the classic physics for many years.

The black body radiation

When we heat a body, this begins to glow. Also when it has not started to glow, it irradiates in the infrared field. The glow can be explained considering that, while heating it, the electrons on the surface of the body get thermally excited and emit light. It has been very hard to explain the radiation spectrum of the light being emitted by black bodies. A black body is a piece of material that emits light corresponding to its temperature. When it is cold it absorbs all radiation. To simulate a similar body we can think to a hollow cavity like that in the following picture.

All the light enters in the hole and it is reflected many times till it gets completely absorbed by the body. By using this model we can study the spectrum of the radiations emitted by the body. You can see the diagram in the following picture.


Trying to solve the puzzle of an enigmatic diagram

On the Y axis you have the Energy while on the X axis there is the wavelength. Nobody was able to describe this spectrum in a classical way.

The first attempt came up with Wilhelm Wien with a formula that was working well for higher λ but failed for lower frequencies.

A second attempt has been the Rayleigh-Jeans Law that was working well for low frequencies but not for higher frequencies (ultraviolet catastrophe).


Plank and the quantization of the energy

Max Planck found a radical solution by making the hypothesis that the quantity of energy that light can exchange with matter is not continuous, as previously expressed by classical physics, but discrete. Planck postulated  in fact that the energy of the light, emitted by the black body cavity, distributes only with multiple integers, according to this relation:

E=nhf where n=0,1,2,3…, h is the Planck constant and f is the frequency of the radiation.

Planck wrote thus this equation to describe the black body spectrum :

His equation is, of course, a perfect description.

The first big result of quantum physics

Planck was saying that electrons, on the surface of the black body, can’t start to oscillate at  just any level of energy, as classical physics supposed. Electrons can reach only specific quantized levels of energy and this energy is a multiple of hf where h is

h=6.626 x10-34Joule*second.

This has been the first big result of quantum physics. But are you sure this situation can’t be explained  under the covering of classical physics?

An explanation by the aid of classical physics

Let’s consider the ether filling the black body cavity with all its invisible particles. The etherons are just waiting in order to start their oscillating movement. When the radiation of light enters the cavity, each etheron acquires an energy of E=hf, that is an energy quantum. It is clear that a quantum of red light contains less energy of a quantum of blue light that has higher frequency.

The ultraviolet catastrophe averted

This way, the black body will absorb all the radiation due to the impact of the etherons against the surface electrons. So it will reach the needed temperature. At this point, it will have energy enough to emit quantum of energy in the infrared or in the yellow field. On the other hand it will not be able to emit an  X or a gamma ray. This way you can explain the reduction of energy emitted in the high frequency field, i.e., the ultraviolet catastrophe.

For the part of the curve with low frequency, the explanation is , at this point, quite obvious. The energy is low, because the frequency is low. The emission of light can once again be explained with an impact between the oscillating electrons with the nearest etherons. The problem is thus that physicists were compelled to describe light emitted by a black body with a particle phenomena description.

Ether and etherons are discrete entities

Once again,  it can be proved that light, described as a wave and moving through particles, can be simply  described  in a classical way. The fact that light is considered  as discrete is not a problem: the mean in which the light passes is discrete and each etheron carries on a discrete energy E=hf.

The wave nature of matter

De Broglie suggested however that not only light has a particle nature beside the wave one. He said that matter has not only a particle nature but also a wave one.

To prove this assertion researchers made an experiment sending an electron beam through a dual slit apparatus and they saw that particles act like a wave .

The central fringe in the picture is heavier because it is the result of the interference. This is the sum of the intensity of the two waves starting from the two slits.

How can you explain the phenomenon on the basis  of the newly reintroduced ether?

The electron beam passes through the ether arriving to the slits. The passage of the electrons transfers energy due to the impact against a number of etherons. So they start oscillating and generate  a wave. The wave generates the interference fringes. Over.

All physics becomes simple with the reintroduction of the ether.


Understood?  Bye, bye my reader.
