Cov electromagnetic spectrum yog qhov txuas ntxiv ntawm txhua tus electromagnetic tsis teem caij raws zaus thiab wavelength. Lub hnub, lub ntiaj teb, thiab lwm lub cev radiates electromagnetic lub zog ntawm qhov sib txawv wavelengths. Electromagnetic lub zog dhau los ntawm qhov chaw ntawm qhov ceev ntawm lub teeb nyob rau hauv daim ntawv ntawm sinusoidal nthwv dej.
Tsis tas li ntawd, lub electromagnetic spectrum yooj yim txhais yog dab tsi?
Txhais ntawm electromagnetic spectrum .: tag nrho ntau ntawm wavelengths lossis frequencies ntawm electromagnetic tawg txuas ntawm gamma rays mus rau lub xov tooj cua ntev tshaj plaws nthwv dej thiab suav nrog lub teeb pom kev.
electromagnetic spectrum ua haujlwm li cas? Electromagnetic hluav taws xob yog tsim thaum lub atom absorbs zog. Lub zog absorbed ua rau ib los yog ntau dua electrons hloov lawv lub zos nyob rau hauv lub atom. Thaum lub electron rov qab mus rau nws qhov qub chaw, ib electromagnetic yoj yog tsim. Cov electrons nyob rau hauv cov atoms no ces nyob rau hauv lub zog siab.
Tom qab ntawd, lo lus nug yog, qhov piv txwv ntawm electromagnetic spectrum yog dab tsi?
Tag nrho electromagnetic spectrum , los ntawm qhov qis tshaj mus rau qhov siab tshaj plaws (ntev tshaj plaws mus rau luv tshaj wavelength), suav nrog txhua lub xov tooj cua nthwv dej (piv txwv li, xov tooj cua lag luam thiab TV, microwaves, radar), infrared hluav taws xob , pom lub teeb, ultraviolet hluav taws xob , X-rays, thiab gamma rays.
Qhov twg yog qhov zoo tshaj plaws txhais ntawm electromagnetic zog?
Electromagnetic (EM) hluav taws xob yog ib daim ntawv ntawm zog uas yog nyob ib ncig ntawm peb thiab siv ntau hom, xws li xov tooj cua tsis, microwaves, X-rays thiab gamma rays. Hnub ci kuj yog ib daim ntawv ntawm EM zog , tab sis pom lub teeb tsuas yog ib feem me me ntawm EM spectrum, uas muaj ntau yam ntawm electromagnetic wavelengths.

Koj txhais li cas los ntawm inertia ntawm kev coj?
Inertia ntawm kev taw qhia txhais tau tias yog qhov tsis muaj peev xwm ntawm lub cev lossis khoom siv los hloov nws txoj kev taw qhia ntawm nws tus kheej. Qhov ntawd yog sab nraud quab yuam yuav tsum tau hloov nws txoj kev taw qhia. Qhov no yog vim inertia ntawm kev coj
Koj txhais li cas los ntawm kev them nyiaj ntawm tRNA?
Kev them nyiaj yug tRNA. Ua ntej ib qho amino acid tuaj yeem muab tso rau hauv ib qho kev loj hlob ntawm polypeptide, nws yuav tsum xub muab txuas mus rau lub molecule hu ua hloov RNA, los yog tRNA, nyob rau hauv ib tug txheej txheem hu ua tRNA them. Tus nqi tRNA yuav nqa cov activated amino acid mus rau ribosome
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Vim li cas qhov absorption spectrum rau chlorophyll a thiab qhov kev ua spectrum rau photosynthesis txawv?
Ib qho kev nqus spectrum qhia tag nrho cov xim ntawm lub teeb absorbed los ntawm cov nroj tsuag. Ib qho kev ua spectrum qhia tag nrho cov xim ntawm lub teeb uas siv hauv photosynthesis. Chlorophylls yog cov xim ntsuab uas nqus liab thiab xiav thiab koom nrog hauv photosynthesis ncaj qha
