Xim ntawm pom lub teeb nyob ntawm nws lub wavelength. Cov wavelengths muaj li ntawm 700 nm ntawm qhov kawg liab ntawm spectrum mus rau 400 nm ntawm violet kawg. Lub teeb dawb yog tiag ua ntawm tag nrho cov xim ntawm zaj sawv vim nws muaj tag nrho cov wavelengths, thiab nws tau piav raws li polychromatic teeb.
Tsis tas li ntawd, lub teeb dawb yog dab tsi?
Lub teeb dawb yog ua Ntawm cov xim hauv qab no: liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab violet. Txhua xim teeb nws muaj nws tus kheej wavelength. Liab teeb muaj qhov ntev wavelength thiab violet teeb muaj qhov luv tshaj wavelength.
Ib yam li ntawd, lub teeb dawb hauv kev tshawb fawb yog dab tsi? Lub teeb dawb txhais tau tias yog qhov sib xyaw ua tiav ntawm tag nrho cov wavelengths ntawm qhov pom spectrum. Qhov no txhais tau tias yog kuv muaj kab teeb teeb ntawm tag nrho cov xim ntawm zaj sawv thiab tsom tag nrho cov xim mus rau ib qho chaw, kev sib xyaw ntawm tag nrho cov xim yuav ua rau lub teeb ntawm lub teeb dawb.
Ib sab ntawm no, Dab tsi Xim yog lub teeb dawb ua los ntawm?
Xya xim ua lub teeb dawb: liab , txiv kab ntxwv daj, ntsuab, xiav , indigo, thiab violet . Cov tub ntxhais kawm ntawv hauv tsev kawm ntawv feem ntau nco cov lus luv luv xws li ROY G BIV, kom nco qab txog xya xim ntawm cov spectrum thiab lawv qhov kev txiav txim. Qee zaum xiav thiab indigo raug kho raws li ib qho xim.
Cov xim dab tsi ua rau pom lub teeb?
Lub teeb pom kev muaj li ntawm 4,000 angstroms txog 7,000 angstroms. Qhov tseeb, cov xim uas ua rau pom lub teeb, zoo li liab , xiav thiab ntsuab , thiab lawv complements violet , daj , thiab txiv kab ntxwv , kuj muaj lawv tus kheej ntau yam ntawm wavelength.

Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Kev pom kev pom hauv computer graphics yog dab tsi?
Kev pom kev pom yog qhov pom ntawm daim duab peb sab uas qhia qhov siab, qhov dav, thiab qhov tob rau cov duab tiag tiag lossis duab
Lub luag haujlwm ntawm photosystem 2 nyob rau hauv lub teeb pom kev yog dab tsi?
Ob lub photosystems nqus lub teeb lub zog los ntawm cov proteins uas muaj cov xim, xws li chlorophyll. Lub teeb-dependent tshwm sim pib hauv photosystem II. Qhov chaw tshuaj tiv thaiv no, hu ua P700, yog oxidized thiab xa cov hluav taws xob hluav taws xob siab kom txo tau NADP + rau NADPH
Qhov txawv ntawm lub teeb dawb thiab lub teeb dub yog dab tsi?
Dub tsuas yog qhov tsis muaj lub teeb, vim tias nws tsis nyob los yog vim nws tau nqus thiab tsis pom. Yog li hu ua 'dub teeb' tsuas yog ultra-violetlight, uas yog lub teeb zoo tib yam (electromagneticradiation) uas yog siab tshaj qhov pom spectrum. Lub teeb twg hu ua lub teeb dawb?
Lub luag haujlwm tseem ceeb ntawm lub teeb pom kev ntawm photosynthesis yog dab tsi?
Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
