Diffraction yog pom ntawm lub teeb nthwv dej tab sis tsuas yog thaum lub nthwv dej ntsib teeb meem nrog me me wavelengths (xws li cov khoom raug tshem tawm hauv peb cov huab cua). Diffraction yog khoov ntawm vuag ncig obstacles thiab qhib. Tus nqi ntawm diffraction nce nrog nce wavelength.
Hais txog qhov no, dab tsi yog dabtsi yog khoov ntawm nthwv dej nyob ib puag ncig los yog los ntawm kev qhib?
Refraction - ib khoov ntawm a yoj raws li nws hla ntawm lub kaum sab xis ntawm ib qho nruab nrab mus rau lwm qhov. Diffraction - qhov khoov ntawm nthwv dej ib ncig ntawm ib qho barrier los yog dhau thiab qhib . Kev cuam tshuam - a yoj kev sib cuam tshuam uas tshwm sim thaum ob lossis ntau dua nthwv dej sib tshooj.
Qhov thib ob, electromagnetic tsis tuaj yeem khoov lub teeb? electromagnetic teeb khoov . Yog li peb paub tias EM teb tsis ua khoov cov paths teeb , tshwj tsis yog rau qhov tsis txaus ntseeg tias lawv lub zog yog nws tus kheej qhov chaw ntawm lub ntiajteb txawj nqus, lossis tias muaj quantum-mechanical photon-photon tawg.
Hais txog qhov no, lub teeb puas khoov ntawm cov khoom?
Diffraction ntawm Teeb : teeb khoov ncig ib khoom . Diffraction yog me ntsis khoov ntawm teeb raws li nws hla ib ncig ntug ib khoom . Tus nqi ntawm khoov nyob ntawm tus txheeb ze loj ntawm lub wavelength ntawm teeb mus rau qhov loj ntawm qhov qhib. Txhawm rau pom qhov no, xav txog teeb nthwv dej li nthwv dej.
Lub teeb nthwv dej puas khoov?
Reffraction yog khoov ntawm txoj kev a lub teeb yoj raws li nws kis los ntawm ib yam khoom mus rau lwm yam khoom. Qhov nyiam ntawm ib txoj kab hluav taws xob teeb rau khoov ib qho kev taw qhia lossis lwm qhov yog nyob ntawm seb qhov lub teeb yoj nrawm los yog qeeb thaum hla tus ciam teb.

Dab tsi yog qhov teeb meem tseem ceeb ntawm ib puag ncig hauv Canada?
Muaj ntau ntau hom teeb meem Environmental hauv Canada uas suav nrog huab cua thiab dej paug, kev hloov pauv huab cua, mining thiab txiav. Cov xwm txheej no tsis yog pom hauv Canada xwb tab sis pom thoob plaws ntiaj teb
Puas yog lub teeb khoov ncig lub ntiaj teb?
Lub teeb khoov ncig ib qho khoom loj yog qhov tshwm sim hu ua Gravitational Lensing. Lub teeb tsis yog 'khoov' tab sis mus rau hauv txoj kab ncaj nraim ntawm qhov nkhaus uas tshwm sim los ntawm qhov chaw gravitational. Gravitational lensing tsis txhais hais tias lub teeb los ntawm lub hnub yuav tsum khoov thiab mus ncig lub ntiaj teb
Lub ntiaj teb nyob rau hauv orbit nyob ib ncig ntawm lub hnub qub uas tsis yog peb lub hnub?
Cov Lus Teb luv luv: Cov ntiaj chaw uas nyob ib puag ncig lwm lub hnub qub hu ua exoplanets. Tag nrho cov ntiaj chaw nyob rau hauv peb lub hnub ci system orbit ncig lub hnub. Cov ntiaj chaw uas nyob ib ncig ntawm lwm lub hnub qub yog hu ua exoplanets. Exoplanets yog qhov nyuaj heev kom pom ncaj qha nrog telescopes
Puas yog tag nrho cov pa oxygen los ntawm lub kiv puag ncig oxygen tuaj ntawm qhov twg?
Cov ntsiab lus: Cov tsos ntawm cov pa dawb nyob hauv lub ntiaj teb huab cua tau coj mus rau Great Oxidation Event. Qhov no tau tshwm sim los ntawm cyanobacteria tsim cov pa oxygen uas tsim los rau hauv ntau cov ntaub ntawv thaum ntxov li 2.3 billion xyoo dhau los
Ib puag ncig ntawm ib lub xov tooj ntawm tes thiab cov kab mob cuam tshuam li cas ntawm cov noob caj noob ces?
Splicing ntawm mRNA nce tus naj npawb ntawm cov protein sib txawv uas lub cev muaj peev xwm tsim tau. Gene qhia yog tswj los ntawm cov proteins uas khi rau cov hauv paus hauv paus hauv DNA. Ib puag ncig ntawm ib lub xovtooj ntawm tes thiab ntawm lub cev muaj feem cuam tshuam rau cov noob caj noob ces
