Qhov sib txawv tseem ceeb ntawm kev nruam thiab kev sib cais yog qhov kev sib txuas tsis tu ncua tsis muaj cov kab sib cais, qhov tsis sib xws muaj cov kab sib cais xwb.
Cov ntsiab lus txuas ntxiv spectrum thiab cov spectrum discrete yog qhov sib txawv ntawm ib leeg. Ib qho spectrum tuaj yeem tsim tau siv cov txiaj ntsig tau txais rau qee qhov ntau ntawm lub cev. Lub xub ntiag los yog tsis muaj qhov sib txawv ntawm cov txiaj ntsig no tuaj yeem tsim kev sib cais lossis ib qho txuas ntxiv, raws li.
Nruam Spectrum yog dab tsi?
Ib qho spectrum txuas ntxiv yog cov txiaj ntsig tau txais txiaj ntsig ntawm lub cev kom muaj nuj nqis, tsis muaj qhov sib txawv ntawm txhua tus nqi. Qhov no tus nqi series yog qhov opposite ntawm lub discrete spectrum. Cov txiaj ntsig coj los tsim kom muaj qhov sib txuas txuas ntxiv tuaj yeem yog lub zog, wavelength, thiab lwm yam.
Qhov piv txwv tshaj plaws rau kev txuas ntxiv yog qhov spectrum ntawm lub teeb tawm los ntawm cov atoms ntawm hydrogen. Cov spectrum no yog tsim los ntawm cov hluav taws xob dawb, uas tau ua khi rau hydrogen ion thiab emit photons uas zoo li kis tau yooj yim hla ntau lub wavelengths.
Lub sij hawm txuas ntxiv spectrum feem ntau yog siv thaum qhov ntau ntawm qhov tseem ceeb rau lub cev muaj nuj nqis (tsuas yog lub zog lossis lub zog) muaj ob qho tib si txuas ntxiv thiab sib cais, tib lub sijhawm lossis lub sijhawm sib txawv. Qhov no yog vim hais tias txoj hauj lwm thiab lub zog ntawm ib tug dawb particle muaj ib tug tas mus li spectrum, thiab thaum lub particle yog confined rau qhov chaw txwv, nws spectrum ua ib tug discrete spectrum. Feem ntau, quantum chemical systems yog txuam nrog cov khoom dawb (piv txwv li atoms hauv cov pa roj, cov hluav taws xob hauv cov kab hluav taws xob, cov hluav taws xob hluav taws xob hauv cov hlau, thiab lwm yam).
Discrete Spectrum yog dab tsi?
Ib qho kev sib cais yog cov txiaj ntsig tau txais txiaj ntsig ntawm lub cev kom muaj qhov sib txawv ntawm txhua tus nqi. Qhov no yog opposite rau qhov nruam spectrum. Hom spectrum no tshwm sim vim electrons poob los ntawm qee lub xeev quantum mus rau lub xeev qis zog.

Feem ntau, quantum chemical systems muaj cov spectra discrete uas feem ntau cuam tshuam nrog cov khoom dawb; yog li ntawd, txoj hauj lwm thiab lub zog ntawm cov khoom dawb yog nyob rau hauv qhov chaw txwv, uas ua rau muaj qhov sib txawv.
Dab tsi yog qhov sib txawv ntawm Nruam thiab Discrete Spectrum?
Ib qho spectrum txuas ntxiv yog cov txiaj ntsig tau txais txiaj ntsig ntawm lub cev kom muaj nuj nqis, tsis muaj qhov sib txawv ntawm txhua tus nqi. Ib tug discrete spectrum yog ib tug series ntawm attainable qhov tseem ceeb ntawm lub cev muaj nuj nqis, muaj ib tug zoo sib txawv ntawm txhua tus nqi. Qhov sib txawv tseem ceeb ntawm kev nruam thiab kev sib cais yog tias ib qho kev sib txuas tsis tu ncua tsis muaj cov kab sib cais, qhov sib cais spectrum tsuas muaj cov kab sib cais xwb. Yog li ntawd, ib tug nruam spectrum yog ib tug tas mus li series thaum lub discrete spectrum muaj cais kab los yog qhov tseem ceeb. Tsis tas li ntawd, ib qho spectrum ntawm cov khoom ci ntsa iab yog ib qho piv txwv ntawm cov spectrum txuas ntxiv thaum qhov nqus los yog emission spectrum ntawm cais atoms ntawm cov khoom siv tshuaj yog ib qho piv txwv ntawm cov spectrum discrete.
Cov hauv qab no infographic qhia qhov sib txawv ntawm qhov txuas ntxiv thiab tsis sib xws hauv daim ntawv tabular.
Summary – Nruam vs Discrete Spectrum
Nruam spectrum thiab discrete spectrum feem ntau suav hais tias yog qhov sib txawv ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm kev nruam thiab kev sib cais yog qhov kev sib txuas tsis tu ncua tsis muaj cov kab sib cais, qhov sib cais spectrum tsuas muaj cov kab sib cais xwb.
