Cov kab hauv nqus spectrum yog tsaus ntuj vim hais tias lub ntsiab siv lub wavelength tshwj xeeb ntawm lub teeb los ua nqus tau thiaj li dhia mus rau siab dua shells nyob rau hauv nws atom.
Yog li ntawd, kab tsaus nti hauv ib lub spectrum txhais li cas?
Thaum peb pom cov kab tsaus nti hauv ib spectrum , lawv sib raug rau qee qhov wavelengths uas ploj lawm vim yog nqus los ntawm cov teeb meem (hauv daim ntawv ntawm atoms / molecules) ntawm lawv txoj kev. Yog li cov kab tsaus sawv cev "tsis muaj lub teeb" hauv a spectrum , tsis muaj qhov tshwj xeeb wavelength (xim) ntawm lub teeb.
Tsis tas li ntawd, qhov nqus kab spectrum yog dab tsi? Absorption kab . Ib kab nqus yuav tshwm nyob rau hauv ib spectrum if ib nqus tau cov khoom yog muab tso rau ntawm ib qhov chaw thiab cov neeg soj ntsuam. Photons nrog lub zog tshwj xeeb yuav yog nqus tau los ntawm ib qho atom, ion lossis molecule yog tias lub zog no sib npaug ntawm qhov sib txawv ntawm cov qib zog.
Kuj tseem yuav paub, vim li cas thiaj muaj ntau cov kab hauv emission spectrum dua li hauv qhov nqus spectrum?
Qhov txawv ntawm nqus thiab emission spectrum yog li ntawd absorption kab nyob qhov twg qhov kaj nqus tau los ntawm lub atom yog li koj pom ib tug poob rau hauv lub spectrum hos emission spectrum muaj spikes hauv spectrum vim atoms tso photons ntawm cov wavelengths.
Muaj pes tsawg kab yuav ua tau nyob rau hauv lub nqus spectrum?
3 kab

Vim li cas lub zog tsaus nti ua rau lub qab ntuj khwb nrawm?
Lub zog tsaus nti tsis ua rau lub ntiaj teb nrawm nrawm vim yog lub zog tawm sab nraud lossis lub zog tiv thaiv lub zog; Nws ua rau lub ntiaj teb nrawm dua vim tias nws lub zog ceev hloov pauv li cas (lossis, qhov tseeb dua, tsis hloov) raws li lub ntiaj teb txuas ntxiv nthuav dav
Vim li cas thiaj siv cov tshuaj tua kab mob hauv cov tshuaj distillation?
Lub hom phiaj ntawm kev sib tsoo granules Saib Lawv nres, uas qhov tshwm sim tam sim ntawd ntawm vapor npuas nyob rau hauv cov kua kub ua rau upwards splashing. Theanti-bumping granules ua raws li lub hom phiaj rau theformation ntawm vapor cia du boiling
Vim li cas qhov absorption spectrum rau chlorophyll a thiab qhov kev ua spectrum rau photosynthesis txawv?
Ib qho kev nqus spectrum qhia tag nrho cov xim ntawm lub teeb absorbed los ntawm cov nroj tsuag. Ib qho kev ua spectrum qhia tag nrho cov xim ntawm lub teeb uas siv hauv photosynthesis. Chlorophylls yog cov xim ntsuab uas nqus liab thiab xiav thiab koom nrog hauv photosynthesis ncaj qha
Yuav ua li cas koj pom qhov sib npaug ntawm qhov nqus ntawm qhov nqus?
X = [Fe(SCN)2+] thiab yuav tsum tau txiav txim los ntawm tus qauv nkhaus. Tom qab ntawd koj tuaj yeem xam qhov sib npaug tas li, Keq, siv qhov sib npaug sib npaug. Tus qauv nkhaus yog ib zajlus ntawm Absorbance piv [Fe(SCN)2+] (Daim duab 8.1). Nws tuaj yeem siv los muab peb cov concentration ntawm cov tshuaj thaum muab cov absorbance
Vim li cas cov dej thiaj li muaj qhov tsis zoo ntawm txoj kab nqes nqes?
Hauv cov duab kos duab, txoj kab nqes ntawm txoj kab nruab nrab ntawm cov khoom thiab cov kua dej yog qhov tsis zoo es tsis zoo. Yog vim li cas yog tias dej yog ib yam khoom txawv txawv nyob rau hauv uas nws lub xeev yog tsawg ntom dua li cov kua hauv lub xeev
