School But it is important to remember: the light suffers no deviation only when it passes from one medium to another. This also occurs when light hits a surface and back, it is diverted, but returned to spread in the same way, it is the reflection of light. In the work of Euclid called Catóptrica, the phenomenon of reflection in plane mirrors, concave and convex had received a proper investigation, but it was the Iraqi physicist and mathematicianAbu-Ali-Al-Hasan Ibn Al Haythan(Al-Hazen) (965-1040 ) who formulated the law of reflection of light, after a thousand years. The Greeks also knew the refraction of light. In the work of Ptolemy appears some experimental results related to this phenomenon, whose means were considered: air and water, air and glass and water glass. However, René Descartes(1956-1650) was the first from his theoretical work, publishing the Law of Refraction in Figure 2: Refraction of Light when changing from one medium to a medium 2 1. According to Law Snell-Descartes: n sin sin A is C, and the incident ray is refracted ray, regarding both normal (N). Figure 2 b: Refraction of Light when changing from one medium to a medium 2 1. According to Law ofSnell-Descartes: n sin sin C is the incident ray and the ray is refracted, both in relation normal (N). Figure 3: Reflection of light in a smooth surface. The angle of incidence ( ) equals the angle of reflection ( Another property is shown by light scattering, which was studied by Isaac Newton. In 1672, Isaac Newton presented to the Royal Society a statement on the scattering of light, in which he says: Electromagnetism

Škola No, važno je imati na umu: svjetlost ne trpi odstupanja samo kad prelazi iz jednog medija u drugi. To se također događa kada svjetlost udari površinu i natrag, to je preusmjeren, ali vratio se proširio na isti način, što je odraz svjetlosti. U radu Euclid zove Catóptrica, fenomen odraz u ravnini zrcala, konkavno i konveksno dobio pravu istragu, ali je iračka fizičar i matematičarAbu Ali al-Hasan ibnal-Haythan (Al-Hazen) (965-1040 ) koji je formulirao zakon refleksije svjetlosti, nakon tisuću godina. Grci su također poznavali refrakcije svjetla. U radu Ptolomeja pojavi neki eksperimentalni rezultati se odnose na ovaj fenomen, čija sredstva su smatrani: zrak, vodu, zrak i staklo i vodu stakla. Međutim, René Descartes(1956-1650) bio je prvi od njegova teorijskog rada, objavljivanje Zakon loma u Slika 2: lom svjetlosti kada se mijenja iz jednog medija u srednjoročnom 2 1. Prema Zakonu Snell-Descartes: n =1 grijehi grijehr. A je C, a incident zraka se lomi zraka, koja se odnosi na normalno (N). Slika 2. b: lom svjetlosti kada se mijenja iz jednog medija u srednjoročnom 2 1. Prema Snell-Descartes zakon: n =1 grijehi grijehr. C je incident ray i zraka se lomi, kako u odnosu normalan (N). Slika 3: Refleksija svjetlosti na glatkoj površini. Kut upada(i) jednaka je kut refleksije(r) Još jedna nekretnina pokazuje rasipanje svjetlosti, što je studirao Isaaca Newtona. U 1672, Isaac Newton predstavljena na Royal Society izjavu na raspršenja svjetlosti, u kojem on kaže: Elektromagnetizam
