Raws li cov kev sib npaug E = n⋅h⋅ν (lub zog = tus naj npawb ntawm photons lub sij hawm Planck lub sij hawm tas li lub zaus ), yog tias koj faib lub zog los ntawm Planck qhov tas li, koj yuav tsum tau txais photons ib ob. Eh = n⋅ν → lub sij hawm n⋅ν yuav tsum muaj units photons / thib ob.
Hauv qhov no, koj yuav pom qhov zaus ntawm emission photon li cas?
Los ntawm txoj kev, lub zaus Ntawm cov duab hluav taws xob tshwm sim tuaj yeem txiav txim siab thaum lub zog paub, raws li Zog = Planck qhov tas li (h) * ceev ntawm lub teeb (c) / wavelength (&). Cov zaus tsis muaj dab tsi tab sis c/& as speed= zaus lub sij hawm wavelength. Yog li, Zog = Planck qhov tsis tu ncua (h) * zaus (v).
Koj puas tuaj yeem muaj qhov tsis zoo? Yog li lub tswv yim ntawm a tsis zoo zaus , thaum peb tham txog rotating vectors, ua rau kev nkag siab zoo. Yog tias peb tig mus rau qhov zoo, zoo li qhov no, koj tuaj yeem hais tias yog qhov zoo zaus . Thiab yog hais tias peb nyob nraum rotating nyob rau hauv lub tsis zoo txoj kev, zoo li no, koj tuaj yeem hais tias yog ib tsis zoo zaus.
Kuj tseem yuav paub, qhov zaus ntawm photon yog dab tsi?
Txhua photon muaj wavelength thiab a zaus . Lub wavelength yog txhais raws li qhov kev ncua deb ntawm ob peaks ntawm hluav taws xob teb nrog tib vector. Cov zaus ntawm photon txhais tau tias muaj pes tsawg wavelengths a photon propagate txhua thib ob. Tsis zoo li electromagnetic yoj, a photon tsis tuaj yeem yog xim.
Koj pom qhov zaus hauv lej li cas?
Cov zaus ntawm cov ntaub ntawv tshwj xeeb yog tus naj npawb ntawm cov sij hawm cov ntaub ntawv muaj nqis tshwm sim. Piv txwv li, yog tias plaub tus tub ntxhais kawm tau qhab nia ntawm 80 hauv lej , thiab ces tus qhab nia ntawm 80 yog hais tias muaj a zaus ntawm 4. The zaus ntawm cov ntaub ntawv tus nqi feem ntau yog sawv cev los ntawm f.

Yuav ua li cas koj xam qhov zaus ntawm zaus thiab feem pua?
Ua li no, faib cov zaus los ntawm tag nrho cov txiaj ntsig thiab muab faib los ntawm 100. Hauv qhov no, qhov zaus ntawm thawj kab yog 1 thiab tag nrho cov txiaj ntsig yog 10. Qhov feem pua yog tom qab ntawd yog 10.0. Cov kab kawg yog qhov feem pua Cumulative
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Yuav ua li cas koj nrhiav tau qhov sib npaug ntawm ib kab uas muab ib tug point thiab ib tug parallel kab?
Qhov sib npaug ntawm kab hauv daim ntawv nqes hav-intercept yog y = 2x + 5. Qhov nqes hav ntawm parallelline yog tib yam: m = 2. Yog li, qhov sib npaug ntawm kab sib npaug yog y = 2x + a. Txhawm rau nrhiav ib qho, peb siv qhov tseeb tias kab yuav tsum dhau los ntawm qhov muab: 5 = (2) ⋅ (− 3) + a
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
