Qhov sib txawv tseem ceeb ntawm infrared thiab ultraviolet hluav taws xob yog tias lub wavelength ntawm infrared hluav taws xob ntev dua qhov pom lub teeb, whereas lub wavelength ntawm ultraviolet hluav taws xob yog luv dua lub wavelength ntawm pom lub teeb.
Infrared thiab ultraviolet hluav taws xob yog ob hom hluav taws xob hluav taws xob. Qhov no txhais tau hais tias cov hluav taws xob tsis muaj hluav taws xob thiab ib qho chaw sib nqus oscillating perpendicular rau ib leeg. Muaj ntau hom hluav taws xob hluav taws xob sib txawv, nyob ntawm qhov wavelength ntawm cov hluav taws xob.
Dab tsi yog Infrared Radiation?
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 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. Cov hluav taws xob thermal emissions 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 muaj qhov siab tshaj plaws wavelength uas yog proportional rau qhov kub thiab txias 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 ua peb qhov loj xws li IR-A, IR-B, thiab IR-C. Cov pab pawg tuaj yeem raug hu ua ze-IR, nruab nrab-IR thiab deb-IR.
Daim duab 01: Thermal Imaging
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 khoom siv pom kev hmo ntuj.
Dab tsi yog Ultraviolet Radiation?
ultraviolet hluav taws xob yog ib hom hluav taws xob hluav taws xob hluav taws xob uas muaj qhov sib txawv ntawm 10 nm - 400 nm. Yog li ntawd, nws muaj luv luv wavelength piv rau qhov pom lub teeb. Peb tuaj yeem sau nws li UV hluav taws xob. Qhov no wavelength ntau yog luv dua li pom ntau tab sis ntev dua li X-ray ntau. Cov hluav taws xob UV tuaj nrog lub hnub ci (kwv yees li 10% ntawm lub hnub ci).
UV hluav taws xob tsis yog hom hluav taws xob ionizing, tab sis nws tuaj yeem ua rau muaj kev cuam tshuam ntawm qee yam tshuaj lom neeg. Ntxiv nrog rau lub hnub ci, peb tuaj yeem tsim hluav taws xob UV los ntawm hluav taws xob arcs lossis teeb tshwj xeeb xws li mercury teeb.
Daim duab 02: Peb Hom UV Radiation uas cuam tshuam rau Ozone Txheej
Feem ntau, UV hluav taws xob nrog luv luv wavelength tuaj yeem ua rau DNA ntawm peb cov hlwb puas. Sunburns yog ib qho kev mob tshwm sim ntawm kev raug UV hluav taws xob los ntawm tshav ntuj. Txawm li cas los xij, qee qhov wavelengths ntawm cov hluav taws xob no tuaj yeem ua rau tsim cov vitamin D hauv cov tawv nqaij.
Qhov txawv ntawm Infrared thiab Ultraviolet Radiation yog dab tsi?
Infrared thiab ultraviolet hluav taws xob yog ob hom hluav taws xob hluav taws xob. Qhov sib txawv tseem ceeb ntawm infrared thiab ultraviolet hluav taws xob yog tias lub wavelength ntawm infrared radiation yog ntev tshaj li qhov pom lub teeb, whereas lub wavelength ntawm ultraviolet hluav taws xob yog luv dua lub wavelength ntawm pom lub teeb.
Ntxiv mus, IR hluav taws xob muaj ntau zaus ntawm 430 THz txog 300 GHz thaum UV hluav taws xob muaj ntau zaus ntawm 30 PHz txog 750 THz.
Hauv qab infographic ntawm qhov sib txawv ntawm infrared thiab ultraviolet hluav taws xob tabulates ntau qhov kev sib piv ntawm ob lub hluav taws xob.
Summary – Infrared vs Ultraviolet Radiation
Infrared thiab ultraviolet hluav taws xob yog ob hom hluav taws xob hluav taws xob. Qhov sib txawv tseem ceeb ntawm infrared thiab ultraviolet hluav taws xob yog tias lub wavelength ntawm infrared radiation yog ntev tshaj li qhov pom lub teeb, whereas lub wavelength ntawm ultraviolet hluav taws xob yog luv dua lub wavelength ntawm pom lub teeb.
