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. Qhov no yog ib tug kis grating. Kuj tseem muaj kev cuam tshuam gratings.
Lub teeb dawb puas tseem ceeb rau kev sib txawv?
Nws yog qhov tseem ceeb tshaj plaws rau kev sib txawv kom tshwm sim. Qhov qhib lossis qhov dav dav yuav tsum sib piv los yog tsawg dua lub wavelength ntawm lub teeb rau cov qauv diffraction tseem ceeb. … Yog tias tag nrho cov xim muaj qhov sib txawv ntawm qhov sib txawv, lub ntuj yuav saib dawb.
Thaum lub teeb dawb siv li cas tus qauv diffraction yuav hloov?
Yuav hloov pauv li cas thaum lub teeb dawb siv hloov lub teeb monochromatic? Cov xim xim yuav raug pom nrog lub ntsej muag dawb ntawm qhov chaw. Tus qauv yuav tsis pom lawm. Cov duab ntawm tus qauv yuav hloov ntawm hyperbolic mus rau ncig.
Yuav ua li cas yog tias koj ci lub teeb dawb rau hauv qhov sib txawv?
Yog lub teeb dawb hla dhau qhov sib txawv ntawm cov kab ntsug, lub teeb tawg mus rau hauv cov xim zaj sawv ntawm sab xis thiab sab laug.
Xim Xim koj xav tias yuav cuam tshuam los ntawm lub kaum loj tshaj plaws?
Tus nqi ntawm qhov sib txawv nyob ntawm qhov wavelength ntawm lub teeb, nrogluv wavelengths yog disfracted ntawm lub kaum sab xis ntau dua qhov ntev (hauv cov txiaj ntsig, xiav thiab violet lub teebyog qhov txawv ntawm lub kaum siab dua li lub teeb liab).
