Qhov zaus ntawm a teeb nthwv dej muaj feem xyuam rau nws cov xim. Xim yog lub ntsiab lus nyuaj uas nws muaj nws tus kheej ntu hauv phau ntawv no. Monochromatic lub teeb tuaj yeem piav qhia los ntawm ib zaus xwb. Laser teeb yog heev ze li ntawm monochromatic.
Yog li ntawd, lub teeb monochromatic yog dab tsi?
Hauv physics, monochromatic piav teeb uas muaj tib yam wavelength yog li ntawd yog ib xim. tawg mus rau hauv Greek keeb kwm, lo lus qhia nws lub ntsiab lus : monos txhais tau tias ib, kroma txhais tau tias xim. Tej yam uas yog tiag tiag yog monochromatic tsis tshua muaj - tshuaj xyuas cov nplooj ntsuab ntawm cov ntoo thiab koj yuav pom ntau qhov sib txawv.
Qhov thib ob, qhov twg muab qhov zoo tshaj plaws monochromatic teeb? Tunable monochromatic lub teeb qhov chaw . Lub teeb qhov chaw thiab monochromator Feem ntau, lub laser yog suav tias yog qhov qhov zoo tshaj plaws monochromatic teeb qhov chaw . Txawm li cas los xij, lasers yog kim kim thiab muab tsuas yog ib lub wavelengths los yog bands me heev.
Ib yam li ntawd, nws yog nug, dab tsi yog lub teeb monochromatic muab piv txwv?
Qhov ntau ntawm wavelengths no yog sib sau ua ke hu ua electromagnetic spectrum. Piv txwv ntawm Monochromatic Lub teeb . Lub laser ntsuab / liab yog ib qho piv txwv ntawm lub teeb monochromatic thaum yooj yim dawb teeb emitted los ntawm lub teeb yog ib qho piv txwv ntawm polychromatic teeb Raws li nws yog ua los ntawm lwm yam monochromes.
Koj pom lub teeb monochromatic li cas?
- Monochromatic lub teeb ci: Cov ntsiab lus hauv lub xeev gaseous emits qee lub teeb ntawm qee qhov wavelengths. Xws li sodium emits ntawm 4890A.
- Lim: Cov lim tuaj yeem siv tau kom tau txais lub teeb ci monochromatic los ntawm lub teeb ci uas muaj ntau yam wavelengths. Nws cais ib lub wavelength ntawm ib lub teeb absorbing qhov seem.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Dab tsi yog lub teeb ci monochromatic physics?
Hauv physics, monochromatic piav qhia lub teeb uas muaj tib lub wavelength yog li nws yog ib xim. tawg rau hauv Greek cov hauv paus hniav, lo lus qhia nws lub ntsiab lus: monos txhais tau tias ib qho, thiab khroma txhais tau tias xim. Tej yam uas yog monochromatic tiag tiag tsis tshua muaj - tshuaj xyuas cov nplooj ntsuab ntawm cov ntoo thiab koj yuav pom ntau qhov ntxoov ntxoo sib txawv
Dab tsi yog qhov txawv ntawm wavelength ntawm lub teeb liab thiab lub teeb violet?
Violet lub teeb yog hluav taws xob hluav taws xob hluav taws xob nrog wavelengths ntawm 410 nanometers thiab lub teeb liab muaj awavelength ntawm 680 nanometers. Qhov ntau ntawm wavelengths (400 - 700 nm) ntawm lub teeb pom kev yog nyob nruab nrab ntawm lub electromagnetic spectrum (Fig.1)
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Qhov wavelengths ntawm lub teeb twg yog muab tawm los ntawm lub teeb fluorescent?
Txij li CFLs tau tsim los muab kev pom dav dav, feem ntau ntawm lub teeb tawm los ntawm CFLs yog nyob rau thaj tsam pom ntawm cov spectrum (kwv yees li 400-700 nm hauv wavelength). Tsis tas li ntawd, CFLs raug tso tawm me me ntawm UVB (280-315 nm), UVA (315-400 nm) thiab infrared (> 700 nm) hluav taws xob
