Huy\u2026 Co?<\/p>\n

Z\u00e1kony o koliz\u00edch vesm\u00edrn\u00fdch t\u011bles a z\u00e1klady po\u010dtu pravd\u011bpodobnosti maj\u00ed spole\u010dn\u00e9ho asi jen to, \u017ee jim ani trochu nerozum\u00edm. Krom\u011b teda chytr\u00e9ho p\u00e1na, kter\u00fd je vymyslel a popsal. Christiaan Huygens byl v\u00fdznamn\u00fdm fyzikem 17. stolet\u00ed. Poch\u00e1zel z Haagu, stal se \u010dlenem Kr\u00e1lovsk\u00e9 spole\u010dnosti. Spolupracoval s jablkem potrefen\u00fdm Isaacem Newtonem a Italem Giovanni Casinim. Christiaan Huygens ale m\u016f\u017ee za v\u00edc v\u011bc\u00ed. T\u0159eba za to, \u017ee tohle zrovna p\u00ed\u0161u.<\/p>\n

HUYGENS\u016eV PRINCIP:Ka\u017ed\u00fd bod vlnoplochy, do n\u011bho\u017e dosp\u011blo vln\u011bn\u00ed v ur\u010dit\u00e9m okam\u017eiku, m\u016f\u017eeme pokl\u00e1dat za zdroj element\u00e1rn\u00edho vln\u011bn\u00ed, kter\u00e9 se z n\u011bj \u0161\u00ed\u0159\u00ed v element\u00e1rn\u00edch vlnoploch\u00e1ch. Vlnoplocha v dal\u0161\u00edm \u010dasov\u00e9m okam\u017eiku je vn\u011bj\u0161\u00ed obalov\u00e1 plocha v\u0161ech element\u00e1rn\u00edch vlnoploch.<\/em><\/p>\n

\"\"Mo\u017en\u00e1 v t\u00e9hle definici rozum\u00edte jen slovn\u00edm spojk\u00e1m, ale nebojte, koukneme se na to nefyzik\u00e1ln\u00edm o\u010dkem. Pozd\u011bji zjist\u00edme, \u017ee je to podobn\u00fd princip, jak\u00fdm se \u0161\u00ed\u0159\u00ed klepy a drby. P\u0159edstavme si \u010d\u00e1stici. \u010c\u00e1stice je hned vedle zdroje vln\u011bn\u00ed, pana O, tedy oscil\u00e1toru. Oscil\u00e1tor rozkmit\u00e1 \u010d\u00e1stici, kter\u00e1 vln\u011bn\u00ed vezme za sv\u00e9 a utvo\u0159\u00ed kolem sebe element\u00e1rn\u00ed vln\u011bn\u00ed a t\u00edm rozkmit\u00e1 \u010d\u00e1stice j\u00ed bl\u00edzk\u00e9. Takov\u00e9 rozkmitan\u00e9 \u010d\u00e1stice potom samy funguj\u00ed jako zdroj a n\u011bjak\u00fd oscil\u00e1tor jim je vysoce n\u011bkde<\/span> jedno.
\n\u010cili pokud to p\u0159evedeme na sousedky – pan\u00ed Olina se Milen\u011b zm\u00edn\u00ed, \u017ee Josef podv\u00e1d\u00ed svou \u017eenu. To samoz\u0159ejm\u011b Milenou rezonuje a chce se pod\u011blit o novinku dal\u0161\u00ed kamar\u00e1dce. Proto Milena pov\u00ed skute\u010dnost o Josefovi Milu\u0161i. Nicm\u00e9n\u011b se chce Milena p\u0159ed Milu\u0161\u00ed bl\u00fdsknout a proto nep\u0159izn\u00e1, \u017ee je drb u\u017e z druh\u00e9 ruky. Vr\u00e1na k vr\u00e1n\u011b sed\u00e1, Milu\u0161e je kopi\u00ed Mileny, a posouv\u00e1 drb d\u00e1l. A op\u011bt si p\u0159imysl\u00ed, \u017ee je drb jen a jen od n\u00ed. Takov\u00e9 vln\u011bn\u00ed se \u0161\u00ed\u0159\u00ed velmi rychle, dokud nenaraz\u00ed na p\u0159ek\u00e1\u017eku. V t\u00e9hle situaci \u010d\u00e1stice a jejich element\u00e1rn\u00ed vln\u011bn\u00ed, kter\u00e9 hrani\u010d\u00ed s p\u0159ek\u00e1\u017ekou, \u201eobte\u010dou“ nepropustn\u00fd p\u0159edm\u011bt a jejich vlnoplochy se d\u0159\u00edve \u010di pozd\u011bji op\u011bt setkaj\u00ed a vznikne zase pravideln\u00e1 v\u00fdsledn\u00e1 vlnoplocha. Inu, je to stejn\u00e9 jako kdy\u017e se domlouvaj\u00ed p\u0159es balk\u00f3n dv\u011b d\u00e1my. Domluv\u00ed se, ale horko t\u011b\u017eko.<\/p>\n
