Teb: Suab nrov , yog longitudinal, txhais tau hais tias lawv oscillate parallel rau cov kev taw qhia ntawm lawv cov lus tsa suab. Vim tsis muaj ib feem ntawm a suab yoj oscillation uas yog perpendicular rau nws cov lus tsa suab, suab tsis tuaj yeem polarized.
Ua raws li qhov no hauv kev xav, cov suab tsis tuaj yeem Polarised?
Suab nrov yog longitudinal ces lawv yuav tsis tau polarized . Unpolarised: lub yoj vibrations tshwm sim nyob rau hauv tag nrho cov dav hlau perpendicular rau cov kev taw qhia ntawm kev mus ncig.
Kuj Paub, qhov twg ntawm cov nthwv dej hauv qab no Tsis tuaj yeem polarized? Tag nrho cov longitudinal nthwv dej zoo li suab thiab lwm yam tsis tuaj yeem polarized vim qhov kev txav ntawm cov khoom yog twb nyob rau hauv ib dimension uas yog cov kev taw qhia ntawm propogation ntawm yoj . Yog li tag nrho cov transverse nthwv dej zoo li electromagnetic nthwv dej tuaj yeem yog polarized.
Ib yam li ntawd, vim li cas qee qhov nthwv dej tuaj yeem Polarized thiab lwm tus tsis?
Thaum transverse nthwv dej muaj lawv hais ib txwm vibrating nyob rau hauv tib lub dav hlau, lub yoj hais tias yog "plane polarized ". Ntev vuag tau tsi be polarized vim hais tias lawv hais vibrate nyob rau hauv tib txoj kev uas cov yoj taug kev. Vuag txav zog los ntawm qhov nruab nrab tsis muaj txav tag nrho nruab nrab.
Cov suab tsis tuaj yeem cuam tshuam?
Kev cuam tshuam ntawm Suab . Ob tug taug kev nthwv dej uas muaj nyob hauv tib qhov nruab nrab yuav cuam tshuam nrog ib leeg. Yog hais tias lawv amplitudes ntxiv, lub cuam tshuam yog hais tias tsim nyog cuam tshuam , thiab kev puas tsuaj cuam tshuam yog tias lawv "tawm ntawm theem" thiab rho tawm.

Vim li cas qhov tsis tuaj yeem ua haujlwm zoo tshaj plaws ntawm pH ze nws pKa?
Hauv lwm lo lus, pH ntawm qhov sib npaug ntawm cov kua qaub (piv txwv li, thaum qhov sib piv ntawm qhov concentration ntawm acid thiab conjugate puag yog 1: 1) yog sib npaug rau pKa. Cov cheeb tsam no yog qhov ua tau zoo tshaj plaws rau kev tiv thaiv kev hloov pauv loj hauv pH thaum cov kua qaub lossis cov hauv paus ntxiv. Lub titration nkhaus visually qhia tsis muaj peev xwm
Vim li cas qee qhov kev hloov pauv tsis tuaj yeem thim rov qab?
Nws yuav ua tsis tau ntawv dua. Koj qhov siab yuav txo qis. Cov no yog cov kev hloov pauv tsis tau. Lawv tsis tuaj yeem thim rov qab txhua. Qhov sib txawv ntawm kev hloov pauv tsis tau thiab hloov tsis tau rov qab. Cov kev hloov pauv hloov tsis hloov Cov kev hloov pauv Feem ntau cov kev hloov ntawm lub cev yog hloov pauv tau. Tag nrho cov tshuaj hloov pauv yog hloov tsis tau
Vim li cas ho tsis tuaj yeem ib kab ntu muaj ob qhov nruab nrab?
Midpoint ntawm ib kab segment Tsuas yog ib kab kab tuaj yeem muaj qhov nruab nrab. Ib txoj kab tsis tuaj yeem txij li nws mus nyob rau hauv ob qho tib si cov lus qhia, thiab yog li tsis muaj qhov nruab nrab. Ib tug raycannot vim nws tsuas muaj ib kawg, thiab li nomidpoint. Thaum ib kab txiav lwm txoj kab rau hauv ob qhov sib npaug nws hu ua bisector
Lub suab tsis tuaj yeem hloov kev coj ua?
Piv txwv li, lub suab nthwv dej tau paub tias cuam tshuam thaum taug kev hla dej. Txawm hais tias lub suab nthwv dej tsis yog qhov hloov pauv raws nraim, nws taug kev los ntawm qhov nruab nrab nrog cov khoom sib txawv; Yog li, yoj yuav ntsib refraction thiab hloov nws cov kev taw qhia
Cov ntaub ntawv dab tsi tuaj yeem ua suab tsis dhau mus?
Lub suab, txawm li cas los xij, tsis tuaj yeem taug kev los ntawm lub tshuab nqus tsev: nws ib txwm yuav tsum muaj qee yam taug kev los ntawm (paub tias yog qhov nruab nrab), xws li huab cua, dej, iav, lossis hlau
