Cov nthwv dej, xws li suab, xav tau qhov nruab nrablos ntawm kev mus ncig, thaum lub tshuab hluav taws xob (saib hluav taws xob hluav taws xob) tsis tas yuav muaj qhov nruab nrab thiab tuaj yeem nthuav tawm los ntawm lub tshuab nqus tsev.. Kev nthuav tawm ntawm nthwv dej los ntawm qhov nruab nrab nyob ntawm qhov nruab nrab lub zog. See also seismic yoj.
Puas ntev nthwv dej xav tau qhov nruab nrab?
Yes, qhov ntev ntawm nthwv dej xav tau qhov nruab nrab mus txuas ntxiv mus.
Yuav ua li cas tsis xav tau qhov nruab nrab?
Electromagnetic nthwv dej txawv ntawm cov tshuab tsis muaj zog uas lawv tsis xav tau qhov nruab nrab los nthuav tawm. Qhov no txhais tau hais tias electromagnetic nthwv dej tuaj yeem taug kev tsis yog los ntawm huab cua thiab cov khoom siv, tab sis kuj los ntawm lub tshuab nqus tsev.
Yuav ua li cas nthwv dej xav tau kev txav nruab nrab?
Mechanical waves xav tau ib qho nruab nrab txhawm rau thauj lawv lub zog ntawm ib qho chaw mus rau lwm qhov. Lub suab nthwv dej yog ib qho piv txwv ntawm lub tshuab hluav taws xob. Lub suab tsis muaj peev xwm taug kev hla lub tshuab nqus tsev.
Puas compressional nthwv dej tuaj yeem hla qhov chaw khoob?
Nkoj nqa lub zog los ntawm qhov chaw tsis muaj lossis hla qhov nruab nrab yam tsis thauj khoom. Thaum tag nrho cov nthwv dej tuaj yeem xa lub zog los ntawm qhov nruab nrab, qee qhov nthwv dej tuaj yeem xa lub zog los ntawm qhov chaw khoob. Ib qho nruab nrab yog cov khoom siv uas cov nthwv dej tuaj yeem mus. Nws tuaj yeem yog khoom, kua, lossis roj.

Koj puas tuaj yeem tsim cov nthwv dej compressional nrog hlua?
Koj tuaj yeem tsim transverse nthwv dej ntawm txoj hlua los ntawm kev txav ib kawg ntawm txoj hlua nce thiab nqis. Koj tsim ib tug transverse nthwv dej los ntawm inducing nyob rau hauv cov hais uas ua raws li ib tug kev sib raug zoo nruab nrab ib tug motion perpendicular mus rau kev taw qhia ntawm propagation.

Nyob hauv nthwv dej ntawm qhov nruab nrab vibrates?
Nyob rau hauv ib tug transverse nthwv dej, hais ntawm nruab nrab vibrate nce thiab nqis perpendicular mus rau cov kev taw qhia ntawm yoj . Nyob rau hauv ib tug longitudinal yoj longitudinal yoj Mechanical longitudinal wavestseem hu ua compressional lossis compression nthwv dej, vim lawv tsim compression thiab rarefaction thaum taug kev los ntawm qhov nruab nrab, thiab siab nthwv dej, vim lawv tsim thiab txo qis hauv siab.
