Kev xav koom nrog kev hloov pauv ntawm cov nthwv dej thaum lawv dhia tawm ntawm qhov thaiv; refraction ntawm nthwv dej muaj kev hloov pauv ntawm cov nthwv dej thaum lawv dhau los ntawm ib qho nruab nrab mus rau lwm qhov; thiab kev txawv txav Koom 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.
Li ntawd, puas yog refraction tib yam li diffraction?
Qhov zoo sib xws ntawm refraction thiab diffraction yog tias ob qho tib si ntawm cov xwm txheej no koom nrog lub peev xwm ntawm nthwv dej los hloov cov kev taw qhia ntawm nws qhov kev nthuav tawm. Yog li cas refraction , nthwv dej hloov kev taw qhia thaum nws hla ciam teb ntawm ob qhov xov xwm. Zaj sawv yog lwm qhov piv txwv ntawm ntuj refraction ntawm qhov pom kev.
Kuj Paub, suab xav li cas? Yuav rov qab, suab reflection yog ib feem ntawm tus thawj suab yoj uas yuav nyob twj ywm rau hauv koj chav. Yog tias xav txog yog cais los ntawm tus thawj suab teeb liab los ntawm tsawg dua. 1 vib nas this, tib neeg pob ntseg yuav hnov lub suab raws li ib tug ntev lub teeb liab hu ua reverberation.
Dhau li ntawm qhov no, qhov kev xav thiab kev cuam tshuam zoo li cas?
Hauv xav txog , cov nthwv dej thaws tawm ntawm qhov chaw. Ntawm qhov tsis sib xws, hauv refraction , cov nthwv dej dhau los ntawm qhov chaw, uas hloov lawv txoj kev ceev thiab kev taw qhia. Hauv xav txog , lub kaum sab xis ntawm qhov xwm txheej yog tib yam li lub kaum sab xis ntawm xav txog . Kev xav tshwm sim nyob rau hauv daim iav, thaum refraction tshwm sim nyob rau hauv lo ntsiab muag.
Qhov twg yog ib qho piv txwv ntawm kev xav?
Reflection yog qhov kev hloov pauv ntawm lub wavefront ntawm ib qho kev sib tshuam ntawm ob qhov kev tshaj tawm sib txawv kom lub wavefront rov qab mus rau hauv nruab nrab los ntawm qhov uas nws pib. Cov piv txwv muaj xws li kev xav ntawm teeb , suab thiab dej nthwv dej.
Pom zoo:
Dab tsi yog qhov txawv ntawm refraction thiab diffraction?
Refraction yog qhov hloov pauv ntawm cov nthwv dej uas tshwm sim thaum nthwv dej taug kev ntawm ib nrab mus rau lwm qhov. Reffraction yeej ib txwm nrog lub wavelength thiab ceev hloov. Diffraction yog qhov khoov ntawm nthwv dej ib ncig ntawm obstacles thiab qhib. Tus nqi ntawm diffraction nce nrog nce wavelength
Dab tsi yog qhov tseeb ntawm kev xav txog kev sib piv refraction?
Reflection suav nrog kev hloov pauv ntawm cov nthwv dej thaum lawv dhia tawm ntawm qhov thaiv. Kev cuam tshuam ntawm nthwv dej cuam tshuam nrog kev hloov pauv ntawm cov nthwv dej thaum lawv dhau los ntawm ib qho nruab nrab mus rau lwm qhov. Refraction, los yog kev khoov ntawm txoj kev ntawm cov nthwv dej, yog nrog los ntawm kev hloov pauv ntawm qhov nrawm thiab qhov ntev ntawm cov nthwv dej
Reflection suab yog dab tsi?
Thaum lub suab txav mus rau hauv ib qho nruab nrab, nws tawm tsam qhov chaw ntawm lwm qhov nruab nrab thiab rov qab mus rau lwm qhov kev coj, qhov tshwm sim no hu ua qhov kev xav ntawm lub suab. Cov nthwv dej yog hu ua qhov xwm txheej thiab cuam tshuam lub suab nthwv dej
Dab tsi yog qhov refraction telescope?
Refracting Telescopes. Lub koob yees duab ntxov tshaj plaws, nrog rau ntau lub koob yees duab amateur niaj hnub no, siv lo ntsiab muag los sib sau ua ke lub teeb ntau dua li tib neeg lub qhov muag tuaj yeem sau tau ntawm nws tus kheej. Lawv tsom rau lub teeb thiab ua kom cov khoom nyob deb pom zoo dua, pom tseeb thiab nthuav dav. Hom telescope no hu ua refracting telescope
Reflection thiab shearing yog dab tsi?
Ib qho kev xav yog kev hloov pauv uas ua rau daim iav duab ntawm ib qho khoom txheeb ze rau qhov axis ntawm kev xav. Peb tuaj yeem xaiv qhov axis ntawm qhov kev xav hauv lub dav hlau xy los yog perpendicular rau lub dav hlau xy. Shear: - Ib qho kev hloov pauv uas slants cov duab ntawm ib yam khoom hu ua shear transformation
