Qhov sib txawv tseem ceeb ntawm lub teeb liab thiab infrared yog lub teeb liab pom, whereas lub teeb infrared tsis pom.
Lub teeb liab yog cov hluav taws xob uas muaj qhov ntev tshaj plaws ntawm lub wavelength ntawm lwm cov wavelengths hauv qhov pom spectrum. Infrared hluav taws xob, ntawm qhov tod tes, yog ib hom hluav taws xob hluav taws xob muaj hluav taws xob muaj qhov sib txawv ntawm 700 nm - 1 nm.
Lub teeb liab yog dab tsi?
Lub teeb liab yog cov hluav taws xob uas muaj qhov ntev tshaj plaws ntawm lub wavelength ntawm lwm cov wavelengths hauv qhov pom spectrum. Hauv lwm lo lus, lub teeb liab qhia qhov qis tshaj plaws piv rau lwm cov xim lub teeb hluav taws xob hauv qhov pom spectrum.
Daim duab 01: Lub Teeb Pom Kev Pom Kev
Cov spectrum pom tau tuaj yeem piav qhia raws li feem ntawm cov hluav taws xob hluav taws xob hluav taws xob uas pom ntawm peb lub qhov muag. Lub teeb no muaj ntau yam wavelengths ntawm 380nm txog 750nm. Cov xim liab muaj lub wavelength ntawm 630-700 nm. Ntau zaus ntawm 400 txog 480 THz. Txawm li cas los xij, peb tsis tuaj yeem txhais cov qhab no kom meej vim tias cov hluav taws xob hluav taws xob feem ntau yog muab raws li qhov txuas mus ntxiv.
Feem ntau, huab cua huv cuam tshuam lub teeb xiav ntau dua li lub teeb liab. Yog li ntawd, lub ntuj nruab nrab tshwm nyob rau hauv xiav xim. Hauv cov khoom siv iav, cov xim liab txav nrawm dua piv rau violet. Yog li ntawd, lub teeb liab beam yog khoov tsawg dua li lub teeb violet. Qhov no yog hu ua refraction ntawm lub teeb, thiab cov xim sib txawv ntawm lub teeb pom kev sib txawv, tsim kom muaj cov xim sib txawv. Cov xim liab yog nyob rau hauv ib qho ntawm qhov pom spectra, thiab lwm qhov kawg muaj xim violet.
Infrared yog dab tsi?
Infrared hluav taws xob yog ib hom hluav taws xob hluav taws xob muaj hluav taws xob muaj qhov sib txawv ntawm 700 nm - 1 000 nm. Yog li ntawd, lub wavelength ntau ntawm cov hluav taws xob no ntev dua li qhov pom lub teeb. Qhov no ua rau qhov hluav taws xob pom tsis tau rau tib neeg lub qhov muag. Cov hluav taws xob hluav taws xob hluav taws xob tuaj yeem sau luv ua IR hluav taws xob. Nws pib ntawm ntug liab ntawm lub teeb pom kev. Thermal hluav taws xob emitted los ntawm ib yam khoom xws li tib neeg lub cev (ze ntawm chav tsev kub) yog emissions nyob rau hauv daim ntawv ntawm IR hluav taws xob. Ntxiv mus, zoo ib yam li txhua hom hluav taws xob hluav taws xob hluav taws xob, IR hluav taws xob muaj qee lub zog, thiab cov hluav taws xob no tuaj yeem ua raws li ob qho tib si yoj thiab particle daim ntawv. Qhov ntau zaus zaus rau qhov hluav taws xob no yog 430 THz txog 300 GHz.

Feem ntau, IR hluav taws xob muaj cov spectrum ntawm wavelengths. Thermal IR hluav taws xob kuj tseem muaj qhov sib npaug rau qhov khoom ntawm qhov kub thiab txias kho ntawm cov khoom uas IR hluav taws xob tawm. Qee qhov me me ntawm IR hluav taws xob band muaj xws li ze-infrared, luv wavelength-infrared, nruab nrab-wavelength-infrared, ntev wavelength-infrared, thiab far-infrared tawg. Txawm li cas los xij, peb tuaj yeem faib cov kab hluav taws xob infrared nyob rau hauv electromagnetic spectrum rau hauv peb qhov loj: IR-A, IR-B, thiab IR-C. Cov bands tuaj yeem raug hu ua ze-IR, nruab nrab-IR, thiab deb-IR.
Feem ntau, IR hluav taws xob yog siv los ua hluav taws xob thermal lossis hluav taws xob kub. Cov hluav taws xob los ntawm lub hnub suav rau 49% ntawm IR wavelengths. Qhov no ua rau cov cua sov ntawm lub ntiaj teb nto. Tsis zoo li lwm txoj hauv kev hloov cua sov, piv txwv li. conduction thiab convection, thermal tawg tuaj yeem hloov cov cua sov los ntawm lub tshuab nqus tsev. IR hluav taws xob uas tawm ntawm tib neeg lub cev yog qhov tseem ceeb hauv kev tsim cov cuab yeej pom kev hmo ntuj.
Qhov txawv ntawm Lub Teeb Liab thiab Infrared yog dab tsi?
Electromagnetic hluav taws xob muaj ntau qhov sib txawv ntawm cov wavelengths uas muaj ntau zaus. Pom pom lub teeb thiab infrared yog ob yam li ntawd. Cov hluav taws xob hluav taws xob yog ib hom hluav taws xob hluav taws xob hluav taws xob uas muaj qhov sib txawv ntawm 700 nm - 1 nm, thaum lub teeb liab yog cov hluav taws xob muaj qhov ntev tshaj plaws ntawm lwm qhov wavelengths hauv qhov pom spectrum. Qhov sib txawv tseem ceeb ntawm lub teeb liab thiab infrared yog lub teeb liab pom thaum lub teeb infrared tsis pom.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm lub teeb liab thiab infrared hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Red Light vs Infrared
Lub teeb liab yog cov hluav taws xob uas muaj qhov ntev tshaj plaws ntawm lub wavelength ntawm lwm cov wavelengths hauv qhov pom spectrum. Infrared hluav taws xob yog ib hom hluav taws xob hluav taws xob hluav taws xob muaj qhov sib txawv ntawm 700 nm - 1 nm. Qhov sib txawv tseem ceeb ntawm lub teeb liab thiab infrared yog lub teeb liab pom, whereas lub teeb infrared tsis pom.
