Nyob rau hauv qhov sib txawv no qhov xwm txheej thiab qhov sib txawv yoj pem hauv ntej yog spherical lossis cylindrical (b) Fraunhoffer diffraction: Hauv fraunhoffer diffraction, lub teeb qhov chaw thiab qhov taw qhia kev soj ntsuam nyob ntawm qhov kev ncua deb ntawm lub teeb meem. uas yog, qhov xwm txheej thiab qhov sib txawv wavefronts yog dav hlau.
Lub wavefront twg yog siv hauv Fresnel diffraction?
Kev piav qhia: Hauv Fresnel Diffraction, kev cuam tshuam tshwm sim ntawm lub teeb nthwv dej mus txog qhov taw tes los ntawm ntau qhov chaw ntawm tib lub wavefront. Yog li, qhov xwm txheej wavefront yog spherical lossis cylindrical.
Dab tsi tshwm sim hauv Fresnel diffraction?
"Fresnel diffraction" txhais tau tias yog qhov tshwm sim ntawm qhov sib txawv qhov twg ntawm ib qho khoom siv hluav taws xob thiab qhov chaw soj ntsuam lossis ob qho tib si nyob ntawm qhov deb kawg ntawm ib qho khoom, yog li qhov xwm txheej nthwv dej lossis tawm nthwv dej tsis tuaj yeem suav tias yog lub dav hlau nthwv dej.
Dab tsi tshwm sim hauv Fraunhofer diffraction?
Thaum ib lub teeb ci ntsa iab los ntawm ib qho kev cuam tshuam, qee qhov ntawm lub teeb tau tawg nyob ib ncig ntawm cov khoom, lub teeb thiab tsaus nti feem ntau pom ntawm ntug ntxoov ntxoo - Cov nyhuv no hu ua diffraction. Cov teebmeem no tuaj yeem ua qauv siv lub hauv paus ntsiab lus Huygens-Fresnel.
Fraunhofer diffraction yog dab tsi piav qhia luv luv?
Fraunhofer diffraction yog hom diffraction uas tshwm sim nyob rau hauv qhov txwv ntawm me me Fresnel naj npawb. Hauv Fraunhofer diffraction, tus qauv diffraction yog ywj siab ntawm qhov kev ncua deb ntawm lub vijtsam, nyob ntawm seb lub kaum sab xis ntawm lub vijtsam los ntawm qhov aperture xwb.
Pom zoo:
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Nyob rau hauv science dab tsi yog qhov sib txawv ntawm qhov txawv?
Qhov txawv txav yog qhov sib txawv uas tau ntsuas lossis sim hauv qhov kev sim.1 Piv txwv li, hauv kev tshawb nrhiav seb qhov kev qhia qhia cuam tshuam li cas cov qhab nia xeem, qhov sib txawv nyob ntawm yuav yog cov neeg koom cov qhab nias xeem, vim qhov ntawd yog qhov ntsuas .
Dab tsi yog qhov sib txawv ntawm qhov sib txawv?
Nyob rau hauv nplooj ntawv no koj tuaj yeem tshawb pom 12 lub ntsiab lus, cov lus sib piv, cov lus qhia tsis zoo, thiab cov lus hais txog qhov tsis sib xws, xws li: antithesis , contraposition contraposition Nyob rau hauv ib txwm logic, contraposition yog ib daim ntawv ntawm tam sim no inference nyob rau hauv uas ib tug proposition yog inferred los ntawm lwm tus thiab qhov twg tus qub muaj rau nws cov ntsiab lus contradictory ntawm tus thawj logical proposition tus predicate
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
