Pafupipafupi phokoso, kuwala ndi zotsatira Doppler

Phokoso pafupipafupi ali ndi makhalidwe chibadidwe cha zinthu zina zochitika zingapo pochulukitsa mwa aziweyulira. Izi ndi zoona Mwachitsanzo, kuwala kapena X-ray. pafupipafupi phokoso - ndi zina thupi wambiri, amene amakhala ndi nambala zonse kubwereza. Amaonekera ndi chiŵerengero chiwerengero cha mafunde kwa imeneyi yaitali imene Yak. Mwachitsanzo, pafupipafupi mawu Mzimuyo msinkhu wake, timamva. Kapena samva, ngati kusinthasintha ndi kupitirira malire a mphamvu zathu kumva - infuraredi kapena ultrasound. Ngati tikulankhula za umuna kuwala, malinga pafupipafupi ake ndipo timaganiza, tikuona mitundu yosiyanasiyana ya sipekitiramu kuchokera wofiira buluu.

Phokoso pafupipafupi ndi mmene Doppler

An chodabwitsa chidwi kugwirizana ndi mtengo ankaona amatchedwa ndi Doppler zotsatira (dzina pambuyo anatulukira-wasayansi). Iwo Tingaone chitsanzo cha mafunde kuwala, koma kuwala kumayendera ndi mkulu (pafupifupi 300,000 makilomita pa wachiwiri), ndipo izi zimapangitsa kukhala kovuta zochita zinthu tsiku ndi tsiku. A kafalitsidwe mathamangidwe cha phokoso appreciably pansipa. Choncho, kodi Doppler zotsatira? Tangoganizani, ngati muli pa akungoonerera wa mumsewu waukulu, ndipo ili pafupi nanu patali galimoto ndi siren ntchito. Pamene akadali kutali, mkokomo siren lidzalira kukometsa kwa inu. Izi zikutanthauza kuti pafupipafupi phokoso ndi otsika. Koma pamene tikuyandikira ilo, mochuluka chidzakula. Inu mukhoza kumva zambiri okwera kamvekedwe kuti kufika pazipita galimoto ndidzadutsa pa inu. Pamene chinthu wadutsa ndipo adzachotsedwa kachiwiri, oti timaganiza za mawu Adzabwera ndi kugwa (kwenikweni, yosalala, ngati kuyandikira pa Zithunzi za). Umu ndi mmene zimakhalira chifukwa chakuti phokoso la lipenga poyamba ngati "kukakwera mmwamba" makina, zomwe shortens mtunda pakati ufa ndi (zitunda) mafunde, ndiponso amapanga kamvekedwe pamwambapa, ndipo m'malo mwake, "akuthawa", kotero kuti yoweyula ngati unali "ankawachotsera". Kwenikweni, zimenezi amatchedwa Doppler kwenikweni.

zotsatira phindu

Koma tisaganize kuti Doppler zotsatira kukhoza mfundo youma ku dziko la electrodynamics. Kudziwa zimenezi chimagwiritsidwa ntchito radars ano wailesi, zomwe ndi zochokera muyeso wa mafurikwense yoweyula. Ndipo chimodzimodzi ogwira ntchito apolisi magalimoto anatsimikiza ndi liwiro kayendedwe ka magalimoto komanso zinthu zina zogwirizana - .. ndege liwiro, otaya mitsinje, etc. Malinga ichi ntchito mfundo ndi zizindikiro kuba pothyola kuti adzatani kayendedwe mu chipinda.

Kupezeka kwa Edwin Hubble

Koma mwina anapeza kwambiri zokhudza mmene aforesaid lamulo Hubble a. Back mu 1929, US zakuthambo Edvin Habbl anatembenuka zakutali ake kumwamba usiku. Kuona nyenyezi lakutali, anapeza chinthu chidwi. Ambiri a nyenyezi izi waphimbika mu aura ena Chifunga wofiira. Ngati mkokomo wa chinthu zikuzimiririka pang'onopang'ono akhoza kumva ife apamwamba, kotero zikuzimiririka pang'onopang'ono mtundu thupi zooneka ndi anthu diso utoto. Izi kwenikweni zikutanthawuza kuti nyenyezi kuuluka kuchoka ife. N'zochititsa chidwi kuti mopitirira a nyenyezi ndi mothamanga kwambiri, izo zikuzimiririka pang'onopang'ono. Ataona izi kwathandiza kwambiri kuti zotchuka kwambiri pakati astrophysicists ano zoti chilengedwe kuwonjezera ndi Big Bang monga chiyambi cha izo.
