Abstract
Krajem 19. stoljeća, ultraljubičasta katastrofa bila je jedna od glavnih okidača velikih promjena u poimanju fizike mikrosvijeta. Klasične teorije nisu bile dostatne u rješavanju problema moderne fizike. RayleighJeansov zakon predstavlja klasičnu teoriju zračenja crnog tijela koja u domenama viših frekvencija daje divergentne nefizikalne izraze za izračenu energiju crnog tijela. Velike promjene dolaze s idejama kvantne fizike, odnosno kvantizacijom energije koja dopušta precizni opis zračenja crnog tijela dan Planckovim distribucijskim funkcijama. Cilj ovog rada jest osposobiti aparaturu potrebnu za mjerenje zračenja crnog tijela te eksperimentalno utvrditi da se zračenje crnog tijela odnosno žarulje ponaša prema Planckovom zakonu. U ovom radu pažnju stavljam na praktični dio osposobljavanja uređaja te provedbu i numeričku analizu dobivenih podataka. Iz provedenih mjerenja zračenja crnog tijela pri raznim temperaturama želim interpolacijskim metodama dobiti kontinuirane ovisnosti detektirane struje o valnim duljinama iz kojih bih zaključio slažu li se dobiveni podatci s teorijom.
Abstract (english)
At the end of the 19th century, ultraviolet catastrophe presented one of the most significant indicators of new theories and the physics of the microscopic scale. Classical theories did not yield accurate results. Rayleigh-Jeans law presents the classical theory of black body radiation which gives divergent nonphysical results in the domain of higher frequencies. Significant changes arrive with the ideas of quantum physics and the quantization of energy which allows accurate description of black body radiation given by Planck’s distribution functions. The goal of this thesis is to repair the apparatus needed for black body radiation measurement and to experimentally determine that the measured radiation is consistent with Planck’s law. Most of the attention is on the practical part and the numerical analysis of the obtained data. From black body radiation measurements at various temperatures, I want to obtain the continuous dependence of the detected current on the wavelengths from which I would conclude whether the obtained data agrees with the theory of black body radiation.
