Prisms thiab gratings yog ob hom kev tshaj plaws ntawm dispersive optics. Qhov sib txawv loj ntawm ob lub ntsiab lus no yog qhov tawg ntawm prisms yog non-linear thaum gratings muaj linear dispersion.
Diffraction gratings yog dab tsi?
Ib diffraction grating yog ib qho khoom siv kho qhov muag uas faib (disperses) lub teeb tsim ntawm ntau ntau qhov sib txawv wavelengths (piv txwv li, lub teeb dawb) rau hauv cov khoom siv lub teeb los ntawm wavelength. Qhov yooj yim tshaj plaws ntawm grating yog ib qho uas muaj ntau qhov sib npaug ntawm qhov sib npaug sib npaug.
Dab tsi yog ob hom diffraction gratings?
Feem ntau muaj ob yam sib txawv ntawm qhov sib txawv ntawm qhov sib txawv - txoj cai grating thiab cov holographic grating.
Diffraction gratings siv rau dab tsi?
Diffraction gratings yog cov khoom siv kho qhov muag uas tau siv hauv cov cuab yeej xws li spectrometers cais lub teeb polychromatic rau hauv cov hauv paus ntsiab lus wavelengths uas nws muaj.
Koj ua li cas diffraction gratings?
BACKGROUND. Lub diffraction grating yog tsim los ntawm ua ntau qhov sib npaug sib npaug ntawm qhov chaw ntawm cov khoom siv pob tshab. Nws yog ib qho ua tau los muab ntau qhov khawb ib xees rau ntawm cov khoom, piv txwv li, cov grating yuav siv tau 6,000 kab / cm rau nws.

Puas yog kev pabcuam kev puas hlwb puas yog poj niam?
Txhua yam saum toj no tau coj qee tus kws tshawb fawb los qhia tias kev pabcuam kev puas hlwb yog inherently "feminized , " 2 , 86 raws li lawv ua ntej yam xws li kev hais lus, kev xav tsis zoo, thiab kev nthuav qhia tus kheej qhov tob uas yog qhov tseem ceeb ntawm kev kho mob (txhua tus neeg raug liam tias yog poj niam zoo).
Leej twg invented diffraction grating?
Los ntawm 1785, Philadelphia inventor David Rittenhouse David Rittenhouse David Rittenhouse yog tus tswv cuab ntawm Pennsylvania los ntawm 1777 txog 1789, thiab nrog cov kev txawj ntse thiab kev pab ntawm George Washington, nws tau los ua thawj tus.
Qhov twg piav qhia yuav ua li cas diffraction grating ua haujlwm?
Ib qhov sib txawv grating yog ib qho khoom siv kho qhov muag, uas cais (disperses) polychromatic lub teeb rau hauv nws cov qauv wavelengths (xim). Qhov teeb meem polychromatic ntawm lub grating yog dispersed kom txhua wavelength yog reflected los ntawm grating ntawm ib tug me ntsis txawv lub kaum sab xis.
Puas yog lub teeb dawb diffraction?
Lub teeb dawb tuaj yeem muab cais ua txhua xya xim loj ntawmtiav spectrum lossis zaj sawv los ntawm kev siv lub diffraction grating lossis prism. Lub diffraction grating cais lub teeb rau hauv cov xim raws li lub teeb dhau los ntawm ntau qhov zoo ntawm cov grating.
Puas diffraction ua zaj sawv?
Diffraction yog hais txog qee yam cuam tshuam ntawm lub teeb nthwv dej. Nws tsis muaj dab tsi ua nrog zaj sawv tseeb, tab sis qee qhov cuam tshuam zoo li zaj sawv (glories) yog tshwm sim los ntawm kev sib txawv. Reflection and Transmission xa mus rau qhov tshwm sim thaum lub teeb taug kev hauv ib qho nruab nrab ntsib ib thaj tsam nrog lwm tus.
