Vim qhov tseem ceeb ntawm cov hluav taws xob infrared yog tshav kub lossis hluav taws xob thermal, txhua yam khoom uas muaj qhov kub thiab txias nyob hauv infrared. Txawm tias cov khoom uas peb xav tias yog txias heev, xws li lub thawv dej khov, tawm infrared.
pom nthwv dej infrared nyob qhov twg?
Infrared radiation (IR), lossis lub teeb infrared, yog hom hluav taws xob hluav taws xob uas tsis pom ntawm tib neeg lub qhov muag tab sis peb tuaj yeem hnov zoo li cua sov. Txhua yam khoom nyob rau hauv lub qab ntuj khwb emit ib co theem ntawm IR hluav taws xob, tab sis ob qhov tseeb tshaj qhov chaw yog lub hnub thiab hluav taws.
Dab tsi yog qhov ntuj tsim ntawm infrared nthwv dej?
wavelength range and sources
Common natural sources are hnub ci hluav taws xob thiab hluav taws kub Cov khoom tsim muaj xws li cov khoom siv cua sov, thiab cov teeb infrared siv thiab hauv tsev thiab hauv infrared saunas rau kev noj qab haus huv. Cov chaw muaj cua sov xws li steel / hlau ntau lawm kuj poob rau hauv cheeb tsam infrared.
Peb qhov chaw ntawm infrared yog dab tsi?
Infrared qhov chaw, nyob rau hauv astronomy, ib yam ntawm ntau yam celestial khoom uas radiate ntsuas lub zog ntawm lub infrared cheeb tsam ntawm lub electromagnetic spectrum. Cov khoom xws li Lub Hnub thiab cov ntiaj chaw, qee lub hnub qub, nebulae, thiab galaxies.
Puas yog infrared nthwv dej txiv neej ua?
Man- made qhov chaw ntawm IR hluav taws xob muaj xws li cov hlau rhuab, molten iav, cov khoom siv hluav taws xob hauv tsev, cov qhov muag teeb pom kev zoo, lub tshuab hluav taws xob hluav taws xob, lub qhov cub, vuam arcs, thiab cov plasma torches.
