Txhua qhov taw qhia ntawm lub wavefront yog qhov chaw ntawm wavelets uas kis tawm mus rau pem hauv ntej ntawm tib lub nrawm raws li nthwv dej nws tus kheej. Lub wavefront tshiab yog kab tangent rau tag nrho cov wavelets.

Dab tsi yog wavelets hauv wavefront?

A wavefront yog qhov chaw ntawm tag nrho cov khoom uas nyob rau theem. … Tag nrho cov ntsiab lus ntawm lub nplhaib ncig yog nyob rau theem, xws li lub nplhaib hu ua wavefront. Lub wavelet yog ib oscillation uas pib ntawm xoom, ces qhov amplitude nce thiab tom qab ntawd txo mus rau xoom.

wavefront propagate li cas?

Lub wavefront yog sawv cev los ntawm qhov chaw nyob ib puag ncig, piv txwv li, los ntawm cov kab hluav taws xob, thiab kev nthuav tawm tau ua tiav los ntawm xa cov rays hla qhov chaw. Wavefront cov duab yog tsim los ntawm cov nqes hav thiab txoj hauj lwm ntawm kev sau ntawm rays.

Dab tsi yog wavelets hauv Huygens txoj cai?

Lub Huygens Txoj Cai hais tias txhua qhov taw qhia ntawm lub ntsej muag yog qhov chaw ntawm wavelets. Cov wavelets no nthuav tawm mus rau pem hauv ntej, ntawm tib lub nrawm raws li qhov chaw nthwv dej. Lub wavefront tshiab yog kab tangent rau tag nrho cov wavelets.

yoj pem hauv ntej thiab theem nrab wavelets yog dab tsi?

Qhov chaw ntawm txhua qhov hauv nruab nrab vibrating hauv tib theem hu ua yoj pem hauv ntej Wf. Cov kev taw qhia ntawm propagation ntawm lub teeb rays ntawm lub teeb yog. perpendicular to Wf. … Qhov no yog hu ua Secondary wavefront. Kev siv Huygens txoj cai los kawmrefraction thiab reflection.
