5. Electrons emitting electromagnetic radiation

When shifting from repose to a state of uniform movement (translation or rotation), the electron suffers either a thrust or a torque, which means that for some time it is subdued to an acceleration. If this acceleration is constant, the electron may suffer a linearly growing increase in it speed (linear or angular), and the effect is reflected in an adapting change according the contents of the emitted e.m.i. The transition from the primitive field to the new one is therefore gradational. This transition zone, which we referred to in picture 2, has a thickness different from zero, being proportional to the acceleration span and spreading through space at speed c of the e.m.i. Then we have a changing field which gradually seems to turn the primitive field into the new field, the latter translating the new behaviour of the electron; and this is nothing but the so-called electromagnetic radiation.

At the lab we often verify that electromagnetic radiation transports energy. What kind of energy? Is it something beyond the e.m.i.? Does the electromagnetic field contain any kind of energy?

In classical physics energy is nothing but a high level construct which portrays the equivalence principle among natural phenomena: “two transformations equivalent to a third one are equivalent between themselves” (MESQUITA, 1993). The relative character of energy defined in such way is present all over classical physics, and this is quite clear in mechanics, both in the conception of kinetic energy and in that of potential energy; it is a little confusing in thermodynamics for it simply portrays an equivalence between heat and work, but never an identity between mechanical energy and thermal energy (MESQUITA, 1995b), which is not always clear for beginners; and there is still the energy studied by classical field theories also portraying an equivalence between transformations promoted either by the field or by other processes, but never an identity between field energy and mechanical energy. It is, after all, a device which works out and translates either a possible identity or the existence of hidden variables.

Unquestionably, the field, as we have seen, transports some information to be translated through measurable effects. Under certain experimental conditions, it is possible to show that the fields of some electromagnetic radiations exhibit certain effects suggesting an application of the equivalence principle above mentioned. In the following sections we shall be studying certain aspects related to some of such effects since they have to do with a possible mechanical-energetic character of electromagnetic radiations.
