Le rhoqo isandi, ukukhanya kunye nesiphumo Doppler

Isandi Ukuxhaphaka neneempawu sibubona ezinye iziganeko eziliqela nasekwandiseni ngokusebenzisa otshangatshangiswayo. Oku kuyinyaniso, umzekelo, ukukhanya okanye -X-reyi. rhoqo isandi - yinto ubuninzi ethile emzimbeni, nto leyo waphawulwa ngezinto eziliqela rhoqo ukuphindaphinda. Ixhomekeka lulwahlulo inani amaza ukuya kwixesha apho zivela. Umzekelo, amaza isandi limisela ukuphakama kwayo, siva. Okanye musa ukuva, ukuba ukuhla ezingaphaya umda izakhono zethu ukuva - infrared okanye ultrasound. Ukuba sithetha amadlozi ukukhanya, ngokuxhomekeke rhoqo kunye kwamaza, siyakwazi ukubona imibala eyahlukeneyo kwiinkalo obomvu oluhlaza.

Isandi frequency kunye nesiphumo Doppler

Buyinto umdla ezinxulumene ixabiso kuqwalaselwa kuthiwa ifuthe Doppler (igama emva kokuba discoverer-Scientist). Oku kubonakala phezu umzekelo amaza okukhanya, kodwa isantya ukukhanya eliphezulu kakhulu (malunga 300,000 neekhilomitha ngomzuzwana), yaye oku kwenza kube nzima ukubona naye kwiimeko zemihla ngemihla. A andise Velocity ye amaza omsindo kulungise ngezantsi. Ngoko ke, yintoni umphumo Doppler? Cinga, ukuba ngaba sibukela wendlela engundoqo, kwaye osenyongweni kuwe kude emotweni kunye siren zokusebenza. Xa kude, i siren igquma kuya kuvakala buthuntu kuwe. Oku kuthetha ukuba komsindo iphantsi. Kodwa njengoko siwenza, kokukhona luya kukhula. Uyakwazi uve ithowuni ophezulu bamisa ngakumbi nangakumbi ukuba efikelela ubuninzi xa imoto ziya ndicande kuni. Xa into sele udlule kwaye uya kususwa kwakhona, ombala umsindo kwakhona kuwa (ngokoqobo, agudileyo, ukuba ukuzoba kwigrafu). Ngoko ke uya ngenxa yokuba nesandi siren ekuqaleni uhlobo 'ukubamba-up "umatshini, leyo shortens umgama phakathi emikhumbini (emile) amaza kwaye yenza ukuba umoya okanye ubunzulu ngasentla, yaye ngoko, phezu koko," ubaleka ", kangangokuba nencum bubonakala ngathi' Walungisa". Enyanisweni, oku kubizwa ngokuba nefuthe Doppler le.

kusebenze

Kodwa simele sicinge ukuba isiphumo Doppler ngandlela inyani owomileyo ukusuka kwihlabathi electrodynamics. Olu lwazi sisetyenziswa ngokubanzi radars odiyo mihla, ezo zisekelwe umlinganiselo ezitsho otshangatshangiswayo. Kwaye ngendlela efanayo nabasebenzi endlela ixhomekeke kwisantya ukuhamba kwezithuthi, kunye nezinye iinkonzo ezifanelekileyo - .. isantya Aircraft, ukuhamba imilambo, njl Ngokutsho kwesi imisebenzi mgaqo alarms burglar ukuba njani kwintshukumo kweli gumbi.

Ukufunyanwa Edwin Hubble

Kodwa mhlawumbi Into ebalulekileyo enxulumene isiphumo ikhankanywe umthetho Hubble kaThixo. Ngowe-1929 ukusuka kwi US ngeenkwenkwezi Edvin Habbl wajika iteleskopu yakhe isibhakabhaka ebusuku. Ukubona imithala ekude, wafumana into enika umdla. Uninzi lwezi galaksi ligutyungelwe an aura of inkungu ethile ebomvu. Njengoko isandi into ibuyela nga uyasiva ephezulu, ngoko iyehla umbala umzimba kubonakala iliso obudaywe yabantu. Oku ngokoqobo lithetha ukuba iminyele ukubhabha kude kuthi. Loo nto inika umdla tyi ke kumnyele na, ngokukhawuleza oko ibuyela. Eyathi kuye negalelo elikhulu kakhulu ethandwa phakathi akhona mihla ingcamango yokuba yonke ukwandisa kunye Big Bang njengoko ekuqaleni kwalo.
