Hauv optics , diffraction grating yog ib kho qhov muag tivthaiv nrog ib tug periodic qauv uas splits thiab disfracts lub teeb mus rau hauv ob peb beams mus txawv tebchaws. Cov xim uas tshwm sim yog ib daim ntawv ntawm cov xim xim.
Hauv qhov no, optics siv dab tsi?
Optics yog ceg ntawm physics uas kawm txog tus cwj pwm thiab cov khoom ntawm lub teeb, nrog rau nws cov kev cuam tshuam nrog cov teeb meem thiab kev tsim cov cuab yeej siv los yog ntes nws. Optics feem ntau piav qhia txog tus cwj pwm ntawm pom, ultraviolet, thiab lub teeb infrared.
lo lus tsom xam txhais li cas hauv optics? Hauv geometrical optics , a tsom , kuj hu ua duab point, yog qhov point uas lub teeb rays originating los ntawm ib tug point ntawm cov khoom converge. Txawm tias cov tsom yog conceptually ib point, lub cev lub tsom muaj ib thaj tsam, hu ua lub voj voog plooj.
Ib yam li ntawd, nws yog nug, dab tsi yog hom optics?
Niaj hnub no, peb yuav kwv yees ua pawg kev tshawb fawb ntawm optics rau hauv peb qhov kev kawm dav dav:
- Geometrical optics, kev kawm ntawm lub teeb li rays.
- Lub cev optics, kev kawm ntawm lub teeb raws li nthwv dej.
- Quantum optics, kev kawm ntawm lub teeb raws li hais.
Lens formula yog dab tsi?
A lens formula tej zaum yuav raug txhais raws li tus qauv uas muab kev sib raug zoo ntawm qhov deb ntawm daim duab (v), qhov deb ntawm cov khoom (u), thiab lub focal ntev (f) ntawm lens.

Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog txhais los ntawm optics hauv physics?
Txhais. Optical physics yog kev kawm txog cov yam ntxwv ntawm lub teeb thiab nws cov kev cuam tshuam nrog cov teeb meem. Qhov no suav nrog classical optical phenomena xws li kev xav, refraction, diffraction thiab cuam tshuam, thiab tseem kawm txog quantum mechanical zog ntawm cov pob khoom ntawm lub teeb hu ua photons
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
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
