In fact, from the works of Maxwell, is evident the electromagnetic nature of light. These jobs unified ideas of Electricity and Magnetism, which until then were studied separately, along with the optics. The three fields of study, became part of the same group: electromagnetic phenomena. The work of Maxwell experimental evidence obtained with experiments by Heinrich Hertz in 1885. Hertz conducted experiments on the propagation of electromagnetic waves as a transmitter using metal tips by which electrical sparks leaped and as receiver, metal coils. In their experiments, demonstrated that such waveswere reflected from metal plates. Despite trying to measure the speed of propagation of these waves, only later other researchers found that this was exactly the same speed of light. The difference was at the wavelength of light fractions of a micron, while the radio waves had a length measured in centimeters to hundreds of meters. This proved that an electric field, even formed in empty space, varies with time, would form chains that produce displacement, around himself, magnetic fields also would travel in space. Thus,they would form electromagnetic waves which propagate in the space at the speed of light. At that time been discovered infrared rays, ultraviolet rays and X-raysAll these showed reflection and diffraction radiation, such as light, so they would all electromagnetic waves that obey the Maxwell equations and it was also shown that the heat was transmitted to terrestrial radiation. Thus,matematizava up the vast field of radiation energy, leaving the way ready for that, in 1900, Max Planck could explain the behavior of the energy radiated by so-called black bodies, initiating what we now call quantum mechanics. Maxwell did not use mechanical models to explain their theories, reinforcing the idea that the mathematical formulation was the only way to at least glimpse the nature of that "something is conserved (energy)." Accordingly, Hertz also left out any mechanical model to insist that only Maxwell's equations could shut down all the knowledge possible about the nature of the airwaves. The final conclusions of classical physics showed that the nature of energy would essentially formal, ie, its reality would be more than the mathematical expressions in their sensible effects. Not that math thing was "the thing itself, which turns", but allowed between-see it. With the discovery of quanta, this conception of power does not change, however, came to show that the nature of the corpuscular energy was closest (nature) than the numbers of (nature) of substances.

Zapravo, iz djela Maxwell, evidentno je elektromagnetsko priroda svjetlosti. Ovi poslovi unificiranih ideje elektricitet i magnetizam, koji su do tada proučavali zasebno, zajedno s optikom. Tri područja istraživanja, postale su dio iste skupine: elektromagnetskih pojava. Rad Maxwell eksperimentalni dokazi dobiveni pokusima Heinrich Hertz 1885. Hertz provodi eksperimente na širenje elektromagnetskih valova kao odašiljač pomoću metalne savjete kojim električne iskre skočio i kao prijemnik, metalne zavojnice. U svojim pokusima, pokazali da su takvi valovisu se odrazili na metalnim pločicama. Unatoč pokušavaju izmjeriti brzinu prijenosa od tih valova, tek kasnije drugi znanstvenici smatraju da je upravo to isto brzina svjetlosti. Razlika je u valnoj duljini od lakih frakcija mikrona, a radio valovi imao duljinu mjeri u centimetrima na stotine metara. To se pokazalo da je električno polje, čak i formirana u praznom prostoru, mijenja se s vremenom, će formirati lance koji proizvode raseljavanje, oko sebe, magnetska polja također će putovati svemirom. Dakle,oni će formirati elektromagnetske valove koji se rasprostiru u prostoru brzinom svjetlosti. U to vrijeme su otkriveni infracrvene zrake, ultraljubičaste zrake i X-zrake Sve su to pokazali refleksije i difrakcije zračenja, kao što je svjetlo, tako da će svi elektromagnetski valovi koji slušaju Maxwellove jednadžbe, a također je pokazalo da je toplina prenosi na zemaljske radijacije. Dakle,matematizava se na ogromnom području energije zračenja, ostavljajući put spreman za to, u 1900, Max Planck mogao objasniti ponašanje energije zrači takozvanim crnim tijelima, iniciranje ono što danas zovemo kvantna mehanika. Maxwell nije mehaničke modele objasniti svoje teorije, jačajući ideju da je matematička formula je bio jedini način da se barem uvid o prirodi da se "nešto se energija (energija)." Prema tome, Hertz je također izostavljena bilo mehanički model da inzistiraju da samo Maxwellove jednadžbe mogao ugasiti sve znanje moguće o prirodi radiovalova. Konačni zaključci klasičnoj fizici pokazalo je da je priroda energije će biti formalno, odnosno, njegova stvarnost će biti više od matematičke izraze u svojim učincima osjetljiv. Nije stvar da je matematika je "stvar po sebi, koji se okreće", alito dopustioizmeđu-vidjeti. Uz otkriće kvanta, ova koncepcija vlast ne mijenja, međutim, došao pokazati da priroda korpuskularni Energija je najbliži (priroda) od brojeva (priroda) tvari.(preuzeto iz Vargas, 1996).
