Cov spectrum ntawm a hnub qub yog tsim los ntawm cov hluav taws xob thermal uas ua rau muaj kev txuas ntxiv spectrum . Cov lub hnub qub emits lub teeb hla tag nrho cov electromagnetic spectrum , los ntawm gamma rays mus rau xov tooj cua tsis. Txawm li cas los xij, hnub qub tsis txhob tawm tib lub zog ntawm txhua lub wavelengths.

Raws li, 3 hom spectra yog dab tsi?

Peb lub ntsiab hom spectra : nruam, nqus, emission.

Tsis tas li ntawd, hom spectra yuav pom los ntawm huab cua zoo siab? Tsis tu ncua Spectrum - Ib qho khoom, kua, los yog ntom gas zoo siab rau tawm lub teeb yuav radiate ntawm tag nrho cov wavelengths thiab yog li tsim ib tug nruam spectrum . Tsawg-density gas zoo siab rau tawm lub teeb yuav ua li ntawd ntawm cov wavelengths tshwj xeeb thiab qhov no ua rau emission spectrum.

Tom qab ntawd, cov hnub qub tsim cov hom spectrum li cas?

Ib qho nqus spectrum yog tsim thaum lub continuum dhau los ntawm "cooler" roj. Photons ntawm tus tsim nyog lub zog yog absorbed los ntawm tus atoms hauv tus gas. Cov atmospheres ntawm hnub qub ua raws li daim pam txias nyob ib puag ncig tus kub sab hauv ntawm a hnub qub yog li ntawd stellar raug spectra yog nqus spectrum.

Dab tsi ntawm spectrum yog hnub ci?

Xws li ib lub spectrum los ntawm lub hnub yog hu ua "pom spectrum", tab sis nws tsuas yog ib feem me me ntawm cov teeb nyob rau hauv electromagnetic spectrum, uas spans energies ntawm xov tooj cua tsis mus rau gamma-rays. Lub spectrum ntawm lub hnub tshwm raws li ib tug nruam spectrum thiab nquag sawv cev raws li qhia hauv qab no.
