Mis feem ntau yog ib qho kev sib sau ntawm me me-protein-coated blobs ntawm cov roj raug tshem tawm hauv dej. Cov blobs no me me txaus los tsim Rayleigh tawg tawg . Yog li ntawd, byshining teeb dhau ib khob ntawm mis nyuj , koj tuaj yeem tau txais cov xim tib yam li saum ntuj.
Kuj tseem paub, koj pom dab tsi thaum koj ci lub teeb ci ntawm sab ntawm lub khob mis?
Teeb nyem ci ntsa iab dhau ib iav ntawm dej thiab mis nyuj . Lub teeb koj thaum kawg tau mus pom thaum koj saib nws los ntawm lwm tus sab iav yog avivid liab-txiv kab ntxwv xim, uas sawv cev rau lub teeb dawb ntawm sunminus lub xiav lub teeb uas tau tawg khiav ri niab.
Ib yam li ntawd, yuav ua li cas rau lub teeb thaum nws hla cov mis nyuj? Thaum ib tug beam ntawm lub teeb dhau los ib mis nyuj daws, ces tawg ntawm teeb yog pom. Qhov no yog hu ua cov nyhuv Tyndall. Qhov no tawg ntawm teeb illuminates txoj kev ntawm lub beam nyob rau hauv lub mis nyuj daws.
Kuj paub, puas gelatin tawg lub teeb?
Lub xiav gelatin (uas yog tiag tiag cyan) absorbsred teeb (tab sis tsis yog xiav lossis ntsuab), yog li lub teeb liab tsis pom. Raws li teeb nkag rau hauv gelatin , qhov hloov pauv hauv nruab nrab ua rau muaj kev hloov pauv ntawm qhov ceev ntawm lub teeb thiab hloov nyob rau hauv lub index ntawm refraction.
Yog vim li cas lub ntuj xiav thiab hnub poob yog reddish?
Cov khoom uas me me piv nrog lub teeb wavelength tawg xiav lub teeb muaj zog dua liab teeb. Vim li no, cov roj molecules me me uas ua rau peb lub ntiaj teb huab cua (feem ntau yog oxygen thiab nitrogen) tawg mus rau hauv lub ntiaj teb. xiav ib feem ntawm tshav ntuj nyob rau hauv tag nrho cov lus qhia, tsim aneffect uas peb pom raws li ib tug ntuj xiav.

Heston qhia tias acow hauv qhov chaw tuaj yeem muab cov mis nyuj uas xav tau rau cov calcium no, tab sis kuj piav qhia tias nws yuav raug nqi ntau lab phaus hauv cov nqi roj ib leeg, kom lawv yuav tsis muaj sia nyob rau g-forces ntawm kev tso tawm thiab, thaum nyob ntawd, lawv yuav noj qhov hnyav ntawm peb astronauts nyob rau hauv nyom txhua hli
Puas yog Dolomite muaj kev tawg lossis tawg?
Dolomite tsis tshua pom muaj nyob rau hauv ib puag ncig niaj hnub sedimentary, tab sis dolostones muaj ntau heev hauv cov ntaub ntawv pob zeb. Lub cev muaj zog ntawm Dolomite Chemical Classification Carbonate Diaphaneity Transparent to translucent Cleavage Perfect, rhombohedral, peb cov lus qhia Mohs Hardness 3.5 txog 4
Cov mis nyuj puas yog ib qho khoom xyaw lossis sib xyaw?
Mis yog sib tov. Mis tsis yog ib yam khoom uas tau teev nyob rau hauv lub sij hawm. Mis tsis yog ib qho kev sib xyaw ua ke, tab sis sib xyaw ntawm cov khoom sib xyaw
Puas yog supernova tawg tawg?
Ib tug supernova (/ˌsuːp?rˈno?v?/ plural: supernovae /ˌsuːp?rˈno?viː/ los yog supernovas, cov ntawv luv: SN thiab SNe) yog qhov muaj zog thiab lub hnub qub tawg tawg. Qhov kev tshwm sim astronomical no tshwm sim thaum lub sij hawm kawg evolutionary theem ntawm lub hnub qub loj heev los yog thaum ib tug dawb dwarf tau tshwm sim rau hauv khiav tawm nuclear fusion
Dab tsi ua rau tawg tawg?
Nyob rau hauv volcanology, ib qho tawg tawg yog ib qho hluav taws kub tawg ntawm hom kev ua phem tshaj plaws. Xws li eruptions tshwm sim thaum muaj roj txaus tau yaj nyob rau hauv lub siab nyob rau hauv ib tug viscous magma xws li uas tshem tawm lava hnyav froths rau hauv volcanic tshauv thaum siab dheev txo qis ntawm lub qhov cua
