Cov emission spectrum ntawm lub hnub . Cov Hnub emits electromagnetic hluav taws xob nyob rau hauv ntau yam ntawm wavelengths. Qhov siab tshaj plaws nyob rau hauv hnub ci emission spectrum yog nyob ntawm 500 nm, nyob rau hauv xiav-ntsuab ib feem ntawm qhov pom spectrum . Raws li pom lub teeb, lub Hnub emits ultra violet hluav taws xob thiab infrared hluav taws xob.

Ib yam li ntawd, hom spectrum twg lub hnub emit?

Cov Lub hnub eits hluav taws xob txoj cai hla lub electromagnetic spectrum , los ntawm lub zog loj heev X-rays rau ultra-ntev-ntev-wavelength xov tooj cua, thiab txhua yam nyob rau hauv-nruab nrab. Lub ncov ntawm qhov emission tshwm sim nyob rau hauv qhov pom ntawm qhov spectrum.

Ib sab saum toj no, qhov spectra no qhia dab tsi txog hom ntsiab hauv lub hnub? Cov spectrum ntawm Hnub thiab cov hnub qub nthuav tawm cov kab ci thiab tsaus hu ua Fraunhofer kab. Cov no tau tshwm sim los ntawm cov ntsiab lus emitting los yog absorbing lub teeb ntawm tej wavelengths. Vim txhua tus keeb emits los yog absorbs lub teeb tsuas yog nyob rau hauv tej wavelengths, cov tshuaj muaj pes tsawg leeg ntawm cov hnub qub yuav txiav txim.

Nyob rau hauv no, lub hnub puas muaj emission los yog nqus spectrum?

Ib hnub qub tso pa tawm los ntawm thermal hluav taws xob, uas yuav kwv yees li sib npaug ntawm lub cev hluav taws xob dub. Txawm li cas los xij ib feem ntawm qhov no spectrum yuav yog nqus tau los ntawm txheej txheej ntawm lub hnub qub no. Yeej muaj tseeb li ntawd nqus kab thiab tso pa tawm cov lus dag coincide, yog li cov frequencies yuav rov tso tawm.

Hom kab spectral twg pom hauv lub hnub spectrum?

Muaj ob hom spectral kab hauv pom ib feem ntawm electromagnetic spectrum : Emission kab - cov no tshwm sim li discrete xim kab , feem ntau nyob rau hauv keeb kwm yav dhau dub, thiab sib haum mus rau qhov tshwj xeeb wavelengths ntawm lub teeb emitted los ntawm ib yam khoom.
