Lub hauv paus ntsiab lus ntawm kev pom kev hmo ntuj tsom iav
Koj yuav tsum nkag siab qhov kev xav ntawm lub teeb kom nkag siab txog kev ua haujlwm ntawm kev pom kev hmo ntuj gadgets. Lub teeb yoj lub zog yog inversely proportional rau nws wavelength; qhov siab dua lub zog, qhov luv lub wavelength. Lub zog ntawm lub teeb pom kev yog muab faib ua liab thiab violet, nrog violet muaj qhov siab tshaj plaws thiab liab muaj qhov qis tshaj. Lub infrared spectrum nyob ib sab ntawm lub teeb pom kev zoo. Peb hom infrared tawg yog qhov txawv:
Thaum muab piv rau lub teeb pom kev, nyob ze infrared muaj qhov ntev ntawm 0.7 mus rau 1.3 microns (1 micron yog sib npaug rau ib lab ntawm ib lub 'meter').
Mid-Infrared Rays (Middle IR) - Mid-infrared rays muaj qhov ntev ntawm 1.3 txog 3 microns. Hauv ntau cov khoom siv hluav taws xob, suav nrog cov chaw taws teeb tswj, ze-infrared thiab nruab nrab-infrared photons tau siv.
Nrog wavelengths li ntawm 3 mus rau 30 microns, thermal infrared rays (tseem hu ua thermal IR) ua rau feem ntau ntawm cov infrared spectrum.
Vim tias thermal infrared yog tawm los ntawm cov khoom es tsis yog qhov cuam tshuam los ntawm lawv, nws txawv ntawm ob hom ntawm infrared. Vim muaj kev hloov kho atomic tshwj xeeb, cov khoom tuaj yeem tawm lub teeb infrared.
