Reflection cuam tshuam nrog kev hloov pauv ntawm nthwv dej thaum lawv dhia tawm ntawm qhov thaiv; refraction ntawm nthwv dej cuam tshuam qhov kev hloov ntawm nthwv dej raws li lawv pass ntawm ib nrab mus rau lwm qhov; thiab diffraction cuam tshuam nrog kev hloov pauv ntawm cov nthwv dej thaum lawv dhau los ntawm qhov qhib lossis ib puag ncig ib puag ncig hauv lawv txoj kev.
Yuav ua li cas thaum lub suab sib txawv?
Diffraction: kev khoov ntawm nthwv dej ib puag ncig me mekev cuam tshuam thiab kis tawm ntawm nthwv dej dhau qhov me me qhib. Diffraction hauv cov xwm txheej zoo li no pab lub suab "khoov ib ncig" cov teeb meem. …
Yuav ua li cas thaum nthwv dej nqus?
Thaum nthwv dej tau nqus los ntawm qhov chaw, lub zog ntawm nthwv dej xa mus rau cov khoom hauv qhov chawQhov no feem ntau yuav nce lub zog sab hauv ntawm cov khoom. Thaum lub teeb dawb ci rau ntawm qhov khoom opaque, qee qhov wavelengths lossis xim ntawm lub teeb raug nqus. Cov wavelengths no tsis pom los ntawm peb ob lub qhov muag.
Yuav ua li cas thaum lub teeb sib txawv?
Diffraction yog qhov khoov me ntsis ntawm lub teeb thaum nws hla ntawm ntug ntawm ib qho khoom. … Lub teeb pom kev sib txawv tuaj yeem tsim cov fringes ntawm lub teeb, tsaus ntuj lossis xim ximCov nyhuv kho qhov muag uas tshwm sim los ntawm qhov sib txawv ntawm lub teeb yog cov nyiaj hauv ob sab phlu qee zaum pom nyob ib puag ncig ntawm ntug huab lossis coronas nyob ib puag ncig lub hnub lossis hli.
Diffracted yoj yog dab tsi?
Wave diffraction yog txheej txheem los ntawm cov nthwv dej lub zog kis mus rau qhov tseem ceeb ntawm kev nthuav dav nthwv dejWave diffraction tshwj xeeb yog cuam tshuam nrog kev hloov pauv ntawm ciam teb xws li ntawm lub taub dej tawg, qhov twg yoj lub zog yog pauv mus rau hauv qhov chaw ntxoov ntxoo los ntawm diffraction.
