Rezime

Svetlost i njena priroda su ved dugo predmet proučavanja.U prošlom veku se formirao stav da je
svetlost elektromagnetne prirode i da pripada određenom delu elektromagnetnog spektra.

Rad se bazira na opštim zakonima u području optičkog dijapazona. Među njima su i zakoni vezani za
prirodu svetlosti. Opis svetlosti se vrši formalizmom geometrijske optike, fizičke optike i kvantne
mehanike.U radu se analiziraju izabrane fizičke zakonitosti, koje se prikazuju pomodu analogija iz drugih
oblasti. Izvršeno je i nekoliko eksperimenata i navedeni primeri primene svetlosti u svakodnevnom
životu, kao i zanimljive teoreme, koje su vezane za život, kojima se mogu dokazati ili primeniti zakoni o
svetlosti.

Ključne reči: svetlost,laseri,koherentnost,elektromagnetno zračenje, refleksija.

Summary

Light and its nature are the subject of experiments for a long time.In the last century a stand was
formed that light was electromagnetic in its nature and it belonged to a particular part of the
electromagnetic spectrum.

The paper is based on the general laws in the field of optical range. Among them are laws related to
the nature of light. Description of light is done by geometric optics, physical optics and quantum
mechanics.The selected physical laws are analyzed in the paper which are shown by analogy from other
fields.A few experiments and application of light are made in everyday life, as well as interesting
theorem, which are related to life, which can be proved and applied using the laws of light.

Key words: light, lasers, coherent, electromagnetic radiation, reflection
