Tsis txhob txiav txim siab tias lub suab yog qhov hloov pauv uas muaj crests thiab troughs. Lub suab nthwv dej taug kev los ntawm huab cua yog qhov tseeb qhov ntev ntawm cov nthwv dej longitudinal nthwv dej Nyob rau hauv cov ntaub ntawv ntawm ib tug longitudinal yoj, ib tugwavelength ntsuas yog ua los ntawm kev ntsuas qhov kev ncua deb ntawm compression mus rau compression tom ntej los yog los ntawm ib tug rarefaction rau tom ntej no rarefaction. Ntawm daim duab saum toj no, qhov kev ncua deb ntawm point A rau point C lossis los ntawm point B mus rau point D yuav yog tus sawv cev ntawm lub wavelength. https://www.physicsclassroom.com › Lub-Anatomy-of-a-Wave
Lub Anatomy ntawm Wave - Chav Kawm Physics
nrog compressions thiab rarefactions. … Tsis txhob yuam kev - suab nthwv cua hla huab cua yog cov nthwv dej ntev.
Yuav ua li cas nthwv dej muaj crests thiab troughs?
ntev nthwv dej
… nthwv dej yog hu ua crest, thiab qhov qis qis yog hu ua trough. Rau longitudinal nthwv dej, cov compressions thiab rarefactions yog analogous rau crests thiab troughs ntawm transverse nthwv dej. Qhov kev ncua deb ntawm cov crests los yog troughs yog hu ua lub wavelength.
Yuav ua li cas yog lub suab nthwv dej?
Qhov siab tshaj plaws ntawm nthwv dej yog hu ua crest, thiab qis tshaj plaws yog lub qhov. Vertical nrug nruab nrab ntawm lub crest thiab lub trough yog lub yoj qhov siab. Kab rov tav nyob nruab nrab ntawm ob lub crests uas nyob ib sab los yog troughs yog hu ua lub wavelength.
Dab tsi yog qhov chaw ntawm ibsuab yoj?
Cov ntsiab lus tseem ceeb ntawm lub suab nthwv dej yog frequency, wavelength thiab amplitude.
Puas lub teeb nthwv dej puas muaj crests thiab troughs?
Electromagnetic nthwv dej muaj crests thiab troughs zoo ib yam li cov dej hiav txwv nthwv dej. Qhov kev ncua deb ntawm crests yog lub wavelength.
