Ib qho kev ntsuas ntawm zaus tawm tsam lub sijhawm ua rau a Doppler nkhaus . Raws li lub satellite dhau mus, qhov zaus tau txais zoo li poob tab sis tsis nyob rau hauv ib qho chaw tas li. Tus nqi ntawm kev hloov pauv yog qhov loj tshaj thaum lub sijhawm ze tshaj plaws thiab, yog tias ntsuas tau, tuaj yeem siv los txiav txim qhov kev ncua deb.

Hauv qhov no, Doppler txoj kev ua haujlwm li cas?

Cov Doppler txheej txheem yog qhov zoo txoj kev rau nrhiav exoplanets. Nws siv cov Doppler cuam tshuam rau kev txheeb xyuas cov lus tsa suab thiab cov khoom ntawm lub hnub qub thiab lub ntiaj teb. Qhov no txhais tau hais tias lub hnub qub thiab lub ntiaj teb gravitationally nyiam ib leeg, ua rau lawv orbit nyob ib ncig ntawm ib qho chaw nruab nrab ntawm ob lub cev.

Ib tug kuj yuav nug, koj txhais li cas los ntawm Doppler hloov? Cov Doppler nyhuv (los yog Doppler hloov ) yog qhov hloov hauv zaus ntawm ib tug nthwv dej nyob rau hauv kev sib raug zoo rau ib tug soj ntsuam uas yog txav mus rau lub yoj qhov chaw. Nws yog lub npe hu ua Austrian physicist Christian Doppler , uas piav txog qhov tshwm sim hauv xyoo 1842.

Ib yam li ntawd, Doppler effect yooj yim txhais li cas?

Cov Doppler nyhuv txhais tau tias yog ib qho kev hloov pauv ntawm qhov zaus ntawm lub suab, lub teeb los yog dej nthwv dej raws li qhov chaw thiab cov neeg soj ntsuam txav mus. Ib qho piv txwv ntawm Doppler nyhuv yog tias qhov zaus ntawm lub suab nce ntxiv thaum lub hauv paus txav ze rau tus neeg soj ntsuam.

Dab tsi ua rau Doppler nthuav dav?

Hauv atomic physics, Doppler nthuav dav yog cov nthuav dav ntawm spectral kab vim qhov Doppler nyhuv ua rau los ntawm kev faib cov nrawm ntawm atom lossis molecules. Txawv velocities ntawm cov emitting hais ua rau sib txawv Doppler hloov, cov nyhuv cumulative uas yog kab nthuav dav.
