Faib cov nthwv dej ceev los ntawm nws qhov zaus, ntsuas hauv Hertz. Piv txwv li, yog tias yoj oscillates ntawm 800 THz, los yog 8 x 10 ^ 14Hz, faib 225, 563, 910 los ntawm 8 x 10^14 kom tau 2.82 x 10^-7 meters. Multiply the wave's wavelength los ntawm ib tug billion, uas yog ces tus naj npawb ntawm nanometers hauv ib 'meter'.
Yog li ntawd, koj pom wavelength hauv NM li cas?
Lub wavelength tuaj yeem yog xam siv cov hauv qab no qauv : wavelength = wavevelocity/frequency. Lub wavelength feem ntau yog qhia nyob rau hauv units of meters. Lub cim rau wavelength yog Greek lambda λ, yog li λ = v/f.
Dab tsi yog qhov wavelength ntau ntawm gamma rays? Gamma rays yog lub zog siab tshaj EM hluav taws xob thiab feem ntau muaj lub zog ntau dua 100 keV, zaus ntau dua 1019 Hz, thiab wavelengths tsawg dua 10 picometers.
Ntawm no, dab tsi yog qhov wavelength hauv nanometers?
Thaum lub wavelength yog nyob rau hauv qhov pom spectrum (therange of wavelengths tib neeg tuaj yeem pom, kwv yees li ntawm 390 nm rau 700 nm ), nws yog hu ua "pom teeb pom kev".
Xim, wavelength , zaus thiab lub zog ntawm lub teeb.
| Xim | Ntsuab |
|---|---|
| (nm) | 530 |
| (THz) | 566 |
| (Μm−1) | 1.89 |
| (eV) | 2.34 |
Yuav ua li cas koj nrhiav tau zaus nyob rau hauv nanometers?
Txoj Kev 1 Zaus ntawm Wavelength
- Kawm cov qauv. Tus qauv rau zaus, thaum muab wavelength thiab qhov nrawm ntawm nthwv dej, sau li: f = V / λ
- Hloov cov wavelength mus rau meters, yog tias tsim nyog.
- Faib qhov tshaj tawm los ntawm lub wavelength.
- Sau koj cov lus teb.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Yuav ua li cas resistors coj nyob rau hauv series thiab nyob rau hauv parallel?
Txhua tus resistor nyob rau hauv ib tug series Circuit Court muaj tib tus nqi ntawm tam sim no ntws los ntawm nws. Txhua tus resistor nyob rau hauv ib qho hluav taws xob sib txuas muaj tib qhov hluav taws xob tag nrho ntawm qhov siv rau nws. Qhov tam sim no ntws los ntawm txhua tus resistor nyob rau hauv ib qho kev sib txuas sib txuas sib txawv, nyob ntawm qhov tsis kam
Lub ntsiab lus twg yog pom nyob rau hauv qhov tsuas yog nyob rau hauv tebchaw quizlet?
Halogens yeej ib txwm pom nyob rau hauv cov xwm txheej incompounds vim hais tias halogens yog heev reactivenonmetals
Yuav ua li cas wavelength muaj feem xyuam rau qhov ceev ntawm lub teeb nyob rau hauv ib tug nruab nrab?
Qhov ceev ntawm lub teeb nyob rau hauv nruab nrab yog v = cn v = c n, qhov twg n yog nws qhov Performance index ntawm refraction. Qhov no txhais tau tias v = fλn, qhov twg λn yog lub wavelength nyob rau hauv nruab nrab thiab hais tias λn=λn λ n = λ n, qhov twg λ yog lub wavelength nyob rau hauv lub nqus tsev vacuum thiab n yog qhov nruab nrab qhov ntsuas ntawm refraction
Yuav ua li cas yog ib co qauv nyob rau hauv landforms nyob rau hauv lub ntiaj teb no?
Cov txheej txheem ntawm lub cev no ua rau cov roob, tiaj, toj, thiab toj siab, plaub hom av loj. Phaj tectonics tuaj yeem tsim cov roob thiab toj roob hauv pes thaum yaig tuaj yeem hnav cov av los tsim cov hav thiab hav zoov
