Lub hauv paus ntsiab lus ntawm kev pom kev hmo ntuj
Yuav kom nkag siab txog lub hauv paus ntsiab lus ntawm cov cuab yeej pom kev hmo ntuj, koj yuav tsum nkag siab lub hauv paus ntsiab lus ntawm lub teeb. Lub zog ntawm lub teeb nthwv dej muaj feem xyuam nrog nws lub wavelength: qhov luv dua lub wavelength, lub zog siab dua. Ntawm cov teeb pom kev zoo, lub teeb violet muaj lub zog siab tshaj plaws, thaum lub teeb liab muaj lub zog qis tshaj. Nyob ib sab ntawm qhov pom lub teeb spectrum yog lub infrared spectrum. Infrared rays muab faib ua peb pawg:
Nyob ze Infrared (ze IR) - ze infrared yog nyob ib sab ntawm lub teeb pom kev, thiab nws qhov wavelength range yog 0.7-1.3 microns (1 micron yog sib npaug rau ib labth ntawm ib lub 'meter').
Mid-Infrared Rays (Middle IR) - Lub wavelength ntawm nruab nrab-infrared rays yog 1.3-3 microns. Nyob ze-infrared rays thiab mid-infrared rays yog siv nyob rau hauv ntau yam khoom siv hluav taws xob xws li cov chaw taws teeb tswj.
Thermal Infrared Rays (Thermal IR) - Thermal infrared rays nyob qhov loj tshaj plaws ntawm infrared spectrum, nrog wavelengths nyob rau hauv lub 3-30 micron ntau.
Qhov sib txawv tseem ceeb ntawm thermal infrared thiab lwm yam ob hom infrared yog tias thermal infrared yog tawm los ntawm cov khoom es tsis xav los ntawm lawv. Cov khoom muaj peev xwm tso tawm lub teeb infrared vim qee qhov kev hloov pauv hauv lawv cov atoms.
