Qhov sib txawv tseem ceeb ntawm incandescence thiab iridescence yog qhov incandescence tshwm sim vim cua sov whereas iridescence tshwm sim vim kev hloov ntawm lub kaum sab xis ntawm lub teeb.
Lub teeb yog hom hluav taws xob hluav taws xob. Nws yog pom ntawm qhov muag liab qab ntawm tib neeg. Lub ntsiab ntawm lub teeb yog lub hnub. Txawm li cas los xij, tuaj yeem muaj qee qhov tshwm sim uas tuaj yeem tsim lossis hloov lub teeb. Incandescence thiab iridescence yog ob yam tshwm sim.
Dab tsi yog Incandescence?
Incandescence yog txheej txheem tsim lub teeb los ntawm cov khoom siv rhuab. Lub teeb no yog nyob rau hauv pom electromagnetic tawg; yog li ntawd, peb pom nws li xim. Tsis tas li ntawd, lwm hom hluav taws xob kuj emit (thermal radiation) los ntawm cov khoom kub, tab sis qhov no tsis yog incandescence. Hauv incandescence, lub teeb yog tsim los ntawm qhov kub thiab txias. Yog li ntawd, nws yog ib yam tshwj xeeb ntawm thermal tawg.
Lub hauv paus ntsiab lus ntawm incandescence yog muab lub zog rau atoms los ntawm cua sov. Thaum cov khoom cua sov, nws hloov xim liab ua ntej (ntawm lub sijhawm no, cov khoom emits hluav taws xob txaus, yog li peb tuaj yeem saib cov xim). Liab yog lub zog qis tshaj plaws nyob rau hauv qhov pom ntau yam uas peb tuaj yeem soj ntsuam. Thaum cua sov ntxiv, nws ua dawb. Peb pom nws dawb vim peb tau muab lub zog txaus rau cov khoom kom cov electrons nyob rau hauv nws muaj zog ntau txoj kev, thiab cov sau los ntawm cov no tshwm li lub teeb dawb.

Piv txwv li, peb tuaj yeem pom qhov muag pom thaum lub qhov rooj hlau tau rhuab mus rau qhov kub siab. Tom qab ntawd cov hlau bar pib ci xim liab thiab txiv kab ntxwv, uas yog pom rau peb. Ntawm no, qee qhov hluav taws xob hluav taws xob muab rau cov hlau bar tau dhau los ua lub zog lub teeb.
Incandescence yog qhov tseem ceeb hauv cov teeb pom kev zoo los tsim lub teeb. Cov qij no muaj cov filament uas tuaj yeem tiv taus kub heev yam tsis muaj melting. Cov filament kuj muaj lub neej ntev. Thaum cua sov no filament, nws emits hluav taws xob uas ntog rau hauv cheeb tsam pom, ua teeb. Txawm li cas los xij, feem ntau ntawm cov hluav taws xob yog tawm hauv qhov infrared hauv spectrum; yog li ntawd, peb hnov cua sov. Qhov no yog vim li cas qhov ua tau zoo ntawm qhov muag teev yog tsawg dua hauv kev tsim lub teeb. Yog hais tias muaj ib lub caij uas muaj peev xwm tiv taus kub heev, cov efficiency yuav siab. Hnub ci kuj yog vim lub hnub ci ntsa iab.
Iridescence yog dab tsi?
Iridescence yog qhov tshwm sim kho qhov muag uas peb pom cov xim sib txawv thaum peb hloov lub kaum sab xis ntawm kev soj ntsuam. Yog tias tsis yog, qhov sib txawv tuaj yeem pom yog tias lub kaum sab xis ntawm lub teeb hloov pauv. Qhov no yog cov cuab yeej ntawm qee qhov chaw. Peb tuaj yeem pom qhov chaw zoo li no hauv qhov xwm txheej ntau. Piv txwv li, npauj npaim tis, plaub ntawm cov noog thiab cov plhaub ntawm qee cov tsiaj, qee qhov ntawm cov nroj tsuag muaj cov khoom no. Qhov laj thawj rau qhov no yog qhov hloov pauv ntawm qhov cuam tshuam ntawm hluav taws xob.

Thaum tus txheej txheem no, qee qhov wavelengths nyob rau hauv qhov teeb meem tshwm sim undergo amplification, thiab ib co attenuate. Yog hais tias ob lub teeb nthwv dej nyob rau hauv theem, lawv yog amplified. Yog tias lawv tawm ntawm theem, kev cuam tshuam kev puas tsuaj tshem tawm lawv. Hauv ntau txheej txheej ntawm cov tsiaj, iridescence tshwm sim. Qhov no yog vim muaj kev cuam tshuam ntawm cov yeeb yaj kiab nyias. Piv txwv li, qhov muag ntawm miv muaj ntau txheej txheej uas txhim kho qhov pom kev hmo ntuj. Yog li ntawd, lawv tsim iridescent metallic zoo li reflections.
Qhov txawv ntawm Incandescence thiab Iridescence yog dab tsi?
Qhov sib txawv tseem ceeb ntawm incandescence thiab iridescence yog qhov incandescence tshwm sim vim cua sov whereas iridescence tshwm sim vim kev hloov ntawm lub kaum sab xis ntawm lub teeb. Tsis tas li ntawd, cua sov yog ib qho tseem ceeb ntawm cov incandescence, tab sis tsis xav tau lub zog cua sov hauv iridescence.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm incandescence thiab iridescence.
Summary – Incandescence vs Iridescence
Incandescence thiab iridescence yog ob txheej txheem uas tuaj yeem tsim lub teeb thiab hloov lub teeb raws li. Qhov sib txawv tseem ceeb ntawm incandescence thiab iridescence yog qhov incandescence tshwm sim vim cua sov whereas iridescence tshwm sim vim kev hloov ntawm lub kaum sab xis ntawm lub teeb.
