Ntsuab : 495–570 nm. Yellow: 570-590nm. Txiv kab ntxwv: 590-620 nm.
Tsis tas li ntawd, lub wavelength ntawm lub teeb ntsuab yog dab tsi?
Cov xim ntawm qhov pom lub teeb spectrum
| Xim | Lub sijhawm wavelength | Lub sijhawm luv |
|---|---|---|
| Liab | 700-635 nm | ~ 430-480 THz |
| Txiv kab ntxwv | ~ 635-590 nm | ~ 480-510 THz |
| Daj | 590-560 nm | ~ 510–540 THz |
| Ntsuab | 560-520 nm | ~ 540-580 THz |
Ib tug kuj yuav nug, dab tsi yog lub wavelength ntawm vibgyor? Wavelengths ntawm Vibgyor Xim
| Xim | wavelength |
|---|---|
| Ntsuab | 500 - 570 |
| Daj | 570 - 590 |
| Txiv kab ntxwv | 590 - 620 |
| Liab | 620 - 720 |
Ntawm no, dab tsi xim yog 500 nm wavelength?
Cov xim ntawm qhov pom lub teeb spectrum
| xim | lub sijhawm wavelength | zaus ib ntus |
|---|---|---|
| liab | 625-740 nm | ~ 480–405 THz |
| txiv kab ntxwv | 590-625 nm | ~ 510–480 THz |
| daj | ~ 565–590 nm | ~ 530–510 THz |
| ntsuab | 500-565 nm | ~ 600-530 THz |
Lub wavelength ntawm violet yog dab tsi?
450 nanometer

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog kev sib raug zoo ntawm wavelength zaus thiab qhov ceev ntawm lub teeb?
Lub wavelength thiab zaus ntawm lub teeb yog ze ze. Qhov siab dua qhov zaus, qhov luv dua lub wavelength. Vim tias txhua lub teeb tsis txav mus los ntawm lub tshuab nqus tsev ntawm tib lub nrawm, tus naj npawb ntawm nthwv dej crests dhau los ntawm ib qho taw tes hauv ib thib ob nyob ntawm qhov wavelength
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
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
