A compression yog ib feem ntawm lub yoj (los yog Slinky) uas yog nias ua ke - qhov no zoo li lub crest lossis ncov ntawm lub yoj . Ib qho tsis tshua muaj tshwm sim yog ib feem ntawm cov yoj (los yog Slinky) uas yog qhov sib nrug tshaj plaws - qhov no zoo li lub trough ntawm yoj.
Tsuas yog li ntawd, dab tsi yog cov khoom ntawm compression yoj?
Hauv ib longitudinal nthwv dej , lub crest thiab trough ntawm ib tug transverse yoj sib raug raws li cov compression , thiab qhov tsis tshua muaj tshwm sim. A compression yog thaum cov hais nyob rau hauv nruab nrab los ntawm uas lub yoj yog taug kev los ze zog ua ke tshaj li nyob rau hauv nws tej yam ntuj tso lub xeev, uas yog, thaum lawv ceev yog loj tshaj.
Ib yam li ntawd, dab tsi yog 2 qhov tseem ceeb ntawm cov nthwv dej ntev? Lesson Summary A compression yog qhov uas cov khoom nruab nrab nyob ze tshaj plaws ua ke, thiab qhov tsis tshua muaj tshwm sim yog qhov uas cov khoom sib nrug deb tshaj plaws. Amplitude yog qhov kev ncua deb ntawm qhov chaw so hauv nruab nrab mus rau nruab nrab ntawm qhov tsis tshua muaj los yog compression. Lub wavelength yog qhov kev ncua deb ntawm ob cov ntsiab lus sib npaug.
Ib yam li ntawd, compression hauv nthwv dej yog dab tsi?
Txawm li cas los xij es tsis txhob crests thiab troughs, longitudinal nthwv dej muaj compressions thiab rarefactions. Compression . A compression yog ib cheeb tsam nyob rau hauv ib tug longitudinal yoj qhov twg cov particle nyob ze ua ke. Rarefaction. Ib qho tsis tshua muaj tshwm sim yog ib cheeb tsam nyob rau hauv longitudinal yoj qhov twg cov particle nyob deb tshaj.
Dab tsi ntawm cov nthwv dej yog compressional?
Mechanical longitudinal nthwv dej kuj hu ua compressional los yog compression nthwv dej , vim lawv tsim compression thiab rarefaction thaum mus los ntawm ib tug nruab nrab, thiab siab nthwv dej , vim tias lawv tsim kev nce thiab txo qis hauv siab.

Dab tsi yog cov yam ntxwv ntawm lub teeb yoj?
Muaj peb lub zog ntsuas ntawm nthwv dej: amplitude, wavelength, thiab zaus. Ib qho kev sim kom meej yog Young qhov kev sim ob npaug, uas pom tau tias lub teeb ci ntawm ob lub qhov nyob rau hauv ib qho screen qhia ib qho kev cuam tshuam tus yam ntxwv ntawm nthwv dej ntawm lub teeb, es tsis yog hais
Dab tsi yog qhov opposite ntawm ib tug compressional yoj?
Longitudinal nthwv dej yog nthwv dej uas qhov kev hloov ntawm qhov nruab nrab yog nyob rau hauv tib txoj kev raws li, los yog cov kev taw qhia rov qab mus rau, cov kev taw qhia ntawm propagation ntawm lub nthwv dej. Lwm hom nthwv dej tseem ceeb yog qhov hloov pauv nthwv dej, nyob rau hauv qhov kev hloov pauv ntawm qhov nruab nrab yog nyob rau ntawm txoj cai kaum rau kev taw qhia ntawm kev nthuav tawm
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog meant los ntawm yoj particle xwm ntawm lub teeb?
Hauv physics thiab chemistry, nthwv dej-particle dual tuav lub teeb thiab teeb meem pom cov khoom ntawm ob lub nthwv dej thiab cov khoom. Lub tswv yim ntawm duality yog rooted nyob rau hauv kev sib cav txog qhov xwm ntawm lub teeb thiab teeb meem yos rov qab mus rau 1600s, thaum sib tw theories ntawm lub teeb tau npaj los ntawm Christiaan Huygens thiab Isaac Newton
Dab tsi yog longitudinal waves ib hom yoj yoj rau?
Hauv cov lus yooj yooj yim, cov nthwv dej ntev yog hom nthwv dej ntawm qhov kev hloov pauv ntawm qhov nruab nrab yog nyob rau tib txoj kev uas cov nthwv dej txav mus. Qhov no txhais tau hais tias particle txav ntawm lub nthwv dej yuav sib npaug rau cov kev taw qhia ntawm lub zog txav
