Dab tsi yog qhov cua sov zoo tshaj plaws rau infrared cua sov raj?

Infrared tshav kub hloov tau tshwm sim los ntawm hluav taws xob, hloov khoom ntawm hluav taws xob hluav taws xob. Thaum nyob deb {{{{{}} Infrared hluav taws xob strikes cov khoom raug cua sov, qee qhov hluav taws xob tau cuam tshuam, thaum qee tus kis tau. Thaum lub wavelength ntawm emitted deb - athed rauv taws, ua rau cov molecules ua rau "resonate"- vibrating thiab tig tsiv teb. Cov kev co thiab kev sib hloov nce cov khoom ntsuas kub, ua tiav cov txiaj ntsig cua sov xav tau. Yog li, dab tsi yog qhov haum tshaj plaws rau cov cua sov infrared?

Infrared hluav taws xob yog hais txog kev tso tawm thiab kis (dispersion) ntawm electromagnetic vuag nrog lub spectrum ntawm 0.7μm thiab 80μm. Qhov kev tawm tsam no thiab kev sib kis tau yog nrog los ntawm qhov sib txawv, kev coj hluav taws xob. Zog hloov pauv tsis tas yuav muaj kev sib pauv nruab nrab thiab tuaj yeem tshwm sim txawm tias nyob hauv lub tshuab nqus tsev. Kev ntsuas hluav taws xob infrared tuaj yeem faib los ntawm wavelength li luv luv, nruab nrab, thiab nthwv dej ntev. Kev npaj thiab kev deb ntawm infrared cua sov tubes sib txawv raws li daim ntawv thov.
