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.
