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.
