Rau ib lub teeb sib luag ntawm lub teeb monochromatic ntawm wavelength 'λ', diffraction yog tsim los ntawm ib slit uas nws qhov dav 'a' yog ntawm qhov kev txiav txim ntawm lub wavelength ntawm lub teeb. Yog tias 'D' yog qhov kev ncua deb ntawm lub vijtsam los ntawm qhov hlais, qhov dav ntawm qhov nruab nrab maxima yuav yog. … 2D ua. D.

Yuav ua li cas hu ua parallel beam of light?

thaum ntau cov rays taug kev mus rau ib leeg, ces peb hu cov rays xws li cov kab hluav taws xob sib txuas ntawm lub teeb Rays. Piv txwv li: 1. Lub hnub ci nkag mus rau hauv ib chav los ntawm lub qhov rais qhib.

Puas yog lub teeb sib luag ntawm lub teeb?

Parallel: Thaum cov rays los ntawm qhov chaw nyob deb mus ncig ua ke mus rau ib leeg hauv ib qho kev taw qhia, nws tsimib lub teeb sib luag. Lub teeb ci los ntawm lub hnub yog ib qho piv txwv ntawm lub teeb sib luag ntawm lub teeb. Convergent: Nyob rau hauv ib tug convergent beam, lub teeb rays los ntawm ib qhov chaw ntawm lub teeb, nws thiaj li sib ntsib los yog converge mus rau ib tug point.

Lub teeb twg yog monochromatic?

Lub lub teeb tawm los ntawm lub laser yog monochromatic, uas yog, nws yog ib lub wavelength (xim). Hauv qhov sib piv, lub teeb dawb zoo tib yam yog kev sib txuas ntawm ntau qhov sib txawv wavelengths (xim xim).

Dab tsi yog monochromatic lub teeb wavelength?

hluav taws xob hluav taws xob uas (a) nyob rau hauv qhov pom lossis ze-pom spectrum thiab (b) qhov tseeb tsuas muaj ib zaus lossis wavelength xwb. … Lub teeb nrog nqaim spectral dav, xws li uas tsim los ntawm lasers, yog xam monochromatic lub teeb, piv txwv li, lub teeb yog suav tias yog ib xim, piv txwv li, ib wavelength
