Thaum nws los pom teeb , cov ntau zaus xim, uas yog violet, kuj muaj lub zog tshaj plaws. Cov tsawg zaus ntawm pom teeb uas yog liab, muaj tsawg zog.
Ib yam li ntawd, hom nthwv dej twg muaj qhov tsawg tshaj plaws?
Xov tooj cua nthwv dej , ntawm qhov tod tes, muaj cov qis tshaj lub zog, ntev wavelengths, thiab qis zaus ntawm tej hom ntawm EM hluav taws xob. Nyob rau hauv kev txiav txim los ntawm siab tshaj rau qis tshaj lub zog, ntu ntawm EM spectrum muaj npe: gamma rays, X-rays, ultraviolet hluav taws xob, pom lub teeb, infrared tawg, thiab xov tooj cua nthwv dej.
Ib yam li ntawd, qhov ntau zaus ntawm lub teeb yog dab tsi? Qhov siab dua zaus , qhov nrawm dua oscillations thiab yog li lub zog ntau dua. Yog li ntawd, lub siab tshaj - zaus ultra-violet teeb (los yog qhov qis tshaj wavelength) yog violet. Txawm li cas los xij, lub siab tshaj - zaus pom teeb yuav tsum roughly xiav.
Hauv qhov no, xim dab tsi muaj lub zog tsawg tshaj plaws?
Liab muaj qhov ntev wavelength yog li ntawd muaj lub zog qis tshaj plaws ntawm tej xim.
Lub teeb zaus yog dab tsi?
Cov zaus yog tus naj npawb ntawm nthwv dej uas dhau ib qho chaw hauv qhov chaw thaum lub sijhawm ib ntus, feem ntau yog ib thib ob. Peb ntsuas nws nyob rau hauv units ntawm cycles (yoj) ib ob, los yog hertz. Cov zaus ntawm pom teeb yog hu ua xim, thiab thaj tsam ntawm 430 trillion hertz, pom li liab, mus rau 750 trillion hertz, pom li violet.

Qhov twg electromagnetic yoj muaj qhov luv tshaj wavelength thiab siab tshaj plaws zaus?
Gamma rays muaj lub zog siab tshaj plaws, qhov luv tshaj wavelengths, thiab cov zaus siab tshaj plaws. Cov xov tooj cua tsis muaj zog, ntawm qhov tod tes, muaj lub zog qis tshaj plaws, qhov ntev tshaj plaws wavelengths, thiab qis tshaj zaus ntawm txhua hom EM hluav taws xob
Lub cheeb tsam dej hiav txwv twg muaj biodiversity loj tshaj plaws thiab lub neej dej hiav txwv tshaj plaws?
Epipelagic cheeb tsam nthuav tawm ntawm qhov chaw mus txog 200m nqes. Nws tau txais ntau lub hnub ci thiab yog li muaj cov biodiversity tshaj plaws nyob rau hauv dej hiav txwv. Nws tseem hu ua thaj tsam twilight vim tias lub teeb txwv tsis pub muaj peev xwm lim tau los ntawm cov dej no
Puas yog lub hom phiaj ua haujlwm ib txwm muaj qhov siab tshaj plaws lossis tsawg kawg?
Lub Hom Phiaj Ua Haujlwm Nws tuaj yeem muaj tus nqi siab tshaj plaws, tus nqi qis kawg, ob qho tib si, lossis tsis yog. Nws tag nrho yog nyob ntawm thaj tsam ua tau. Muaj ob hom kev sib txawv ntawm cheeb tsam: thaj tsam uas muaj ciam teb thiab tsis muaj thaj tsam. Qhov tsawg kawg nkaus lossis siab tshaj tus nqi ntawm lub hom phiaj ua haujlwm ib txwm tshwm sim ntawm qhov chaw ntawm thaj tsam ua tau
