Yog tias qhov kev xav sab hauv yuav tsum yog tag nrho, yuav tsum tsis muaj kev hloov pauv ntawm evanescent nthwv dej evanescent nthwv dej Hauv optics thiab acoustics, evanescent nthwv dej yog tsim thaum nthwv dej taug kev hauv nruab nrab ntawm tag nrho cov kev xav sab hauv ntawm nws ciam tebvim lawv ntaus nws ntawm lub kaum sab xis ntau dua li qhov hu ua lub kaum ntse ntse. https://en.wikipedia.org › wiki › Evanescent_field
Evanescent teb - Wikipedia
. … Qhov tshwm sim no yog hu ua kev ntxhov siab tag nrho cov kev xav sab hauv (qhov "frustrated" negates "tag nrho"), abbreviated "frustrated TIR" los yog "FTIR".
TIR tag nrho cov kev xav sab hauv yog dab tsi piav qhia luv luv?
Txhua qhov kev xav sab hauv, hauv physics, ua tiav qhov kev xav ntawm lub teeb ci hauv nruab nrab xws li dej lossis iav los ntawm qhov chaw ib puag ncig rov qab mus rau hauv nruab nrab. Qhov tshwm sim tshwm sim yog lub kaum sab xis ntawm qhov tshwm sim ntau dua li lub kaum ntse ntse, hu ua lub kaum ntse ntse.
Dab tsi yog piv txwv ntawm tag nrho cov kev xav sab hauv?
Qee yam piv txwv ntawm tag nrho cov kev xav sab hauv hauv lub neej niaj hnub yog kev tsim ntawm mirage, ci ntsa iab ntawm lub raj khoob hauv dej, ci ntsa iab hauv lub khob iav, ci ntsa iab ntawm pob zeb diamond, kis ntawm lub teeb rays nyob rau hauv ib tug optical fiber, thiab lwm yam.
Yuav ua li cas rau tag nrho kev xav sab hauv?
Cov xwm txheej rau tag nrho cov kev xav sab hauv
Thaum lub teebtaug kev los ntawm qhov nruab nrab denser, piv txwv li iav, mus rau qhov nruab nrab ntom ntom, piv txwv li huab cua, qhov ceev ntawm lub teeb nce thiab lub teeb refracs deb ntawm qhov qub. Lub kaum sab xis ntawm refraction yog ntau dua lub kaum sab xis ntawm qhov xwm txheej.
Dab tsi tuaj yeem xav txog sab hauv?
Tag nrho cov kev xav sab hauv yuav tsis tshwm sim tshwj tsis yog tias teeb pom kev zooyog taug kev hauv qhov nruab nrab optically ntom ntom rau qhov nruab nrab tsis pom qhov pom tseeb. TIR yuav tshwm sim rau lub teeb tawm ntawm dej mus rau saum huab cua, tab sis nws yuav tsis tshwm sim rau lub teeb taug kev los ntawm huab cua mus rau dej.
