School What is the light anyway? The study of physical phenomena about light and the investigation into its nature emerged from ancient civilizations. She was related to the fire, and sometimes associated with a goddess. The Greeks were the thinkers who gave the most significant contributions in order to explain its nature. According to the Greek philosopher Aristotle(384-322 BC) the light was a disturbance in a material medium. He described a model that can be considered as the embryo of the wave theory of light, as this disorder, it is still a wave. His theory is accepted for a long time. The English scientist and mathematician Isaac Newton(1642-1727), anchored in mechanical theory, formulated a corpuscular theory, ie, the light was composed of particles. According to Newton, a light source emitting particles, extremely small and fast. As a result, your speed should be higher in water than in air. Know why later. Another researcher in this area, Dutchman Cristhian Huygens(1629-1695), said that the light was not a set of particles, but oscillations that propagated through waves. The theory proposed by Huygens, in a book called Treaty of light (1690), indicates the existence of an alleged substance, transparent medium permeating the entire universe, the idea of returning "quintessence": the ether. As a wave is a disturbance in a material medium, the oscillation of the ether is what we see as light. While accepting that the light particles could vibrate, Newton did not accept the wave theory. Thus, Newton and Huygens ... Reached the spot light where truth esplendia their fires. Was divided into halves different from one another. (Andrade, Carlos Drummond de) And then who would have reason Newton and Huygens? As Newton explained the behavior of light, from his corpuscular theory? The refraction of the light passing from one medium to another with different characteristics, which results in a deviation of the light particles. This occurs because the interaction forces between the particles and the particles of the medium in which they propagate in water, for example. Like any force acting on a moving particle can change its speed, these light particles have velocities differ- Electromagnetism

Škola Što je svjetlost svejedno? Proučavanje fizikalnih fenomena na vidjelo i istrage u svojoj prirodi nastao iz drevnih civilizacija. Bila je u vezi s vatre, a ponekad povezana s božicom. Grci su mislioci koji su dali najznačajniji doprinos kako bi se objasniti svoju prirodu. Prema grčkog filozofa Aristotela(384-322 BC), svjetlost je bila smetnja u materijalnom mediju. On je opisao model koji se može smatrati kao zametak valnoj teoriji svjetlosti, što je ovaj poremećaj, to je još uvijek val. Njegova teorija je prihvaćena za dugo vremena. Englezi znanstvenik i matematičar Isaac Newton(1642-1727), usidrena u mehaničkom teoriji, formulirao korpuskularni teoriju, odnosno, svjetlost se sastoji od čestica. Prema Newtonu, izvora svjetlosti emitirajući čestice, iznimno mali i brzi. Kao rezultat toga, vaša brzina bi trebao biti veći u vodi nego u zraku. Znate li zašto kasnije. Još jedan istraživač u ovom području, Dutchman Cristhian Huygens(1629-1695), rekao je da je svjetlost nije skup čestica, ali oscilacije koje propagira kroz valove. Teorija predlaže Huygens, u knjizi pod nazivom Ugovor svjetlosti (1690), ukazuje na postojanje navodnog tvari, transparentno srednje prožima cijeli svemir, ideja povratka "srž": eter. Kao val je poremećaj u materijalnom mediju, oscilacija u eter je ono što mi vidimo kao svjetlost. Iako prihvaća da svjetlosni čestice mogle tresti, Newton nije prihvatio teoriju val. Dakle, Newton i Huygens ... Postignut spot svjetlo gdje je istina esplendia njihovi požari. Bila podijeljena na polovice različite jedna od druge. (Andrade, Carlos Drummond de) I onda tko bi imao razlog Newton i Huygens? Kao što je Newton objasnio ponašanje svjetlosti, iz njegova korpuskularnom teorije? Lom prolaz svjetlosti s jednog medija na drugi s različitim karakteristikama, što rezultira odstupanje od lakih čestica. To se događa zato što sile interakcije između čestica i čestica u mediju u kojem se razmnožavati u vodi, na primjer. Kao i svaka sila djeluje na kretanje čestica može promijeniti svoju brzinu, te čestice imaju svjetlosne brzine razlikuju- Elektromagnetizam
