Node : Ib lub pas dej ua ke ntawm ib lub nthwv dej uas lub nthwv dej muaj qhov tsawg kawg nkaus amplitude. Antinode : Ib qho taw qhia raws ib nthwv dej sawv ntsug uas lub nthwv dej muaj qhov siab tshaj plaws amplitude.

Raws li txoj cai, lub suab nrov ntawm node lossis Antinode?

Piav. Suab yog tsim los ntawm variation ntawm siab thiab nws yog nrov dua qhov twg qhov kev hloov pauv siab tshaj plaws. Lub hom phiaj yog siab tshaj plaws ntawm nodes thiab li no lub siab, yog li ntawd lub suab yog nrov ntawm nodes.

Ib sab saum toj no, dab tsi nthwv dej yog resonance? Resonant Lub Teeb Zaus nthwv dej los ntawm kev vibration ntawm charged hais. Cov khoom, cov khoom them nqi, thiab cov tshuab tshuab feem ntau muaj qee zaus uas lawv nyiam vibrate. Qhov no yog hu ua lawv suab nrov zaus, los yog lawv tej zaus. Qee yam khoom muaj ob lossis ntau dua suab nrov zaus.

Tsis tas li ntawd, cov nodes ua li cas?

Cov nodes thiab antinodes nyob rau hauv ib tug sawv yoj qauv (zoo li tag nrho cov ntsiab lus raws nruab nrab) yog tsim raws li qhov tshwm sim ntawm kev cuam tshuam ntawm ob lub nthwv dej. Cov nodes raug tsim nyob rau hauv qhov chaw uas muaj kev cuam tshuam kev puas tsuaj tshwm sim. Antinodes, ntawm qhov tod tes, yog tsim nyob rau hauv qhov chaw uas muaj kev cuam tshuam tshwm sim.

Dab tsi yog cov nodes hauv physics?

A node yog ib qho taw qhia raws nthwv dej sawv ntsug qhov twg nthwv dej muaj qhov tsawg kawg nkaus amplitude. Piv txwv li, hauv ib txoj hlua vibrating guitar, qhov kawg ntawm txoj hlua yog nodes . Qhov opposite ntawm a node yog anti- node , ib qho chaw uas lub amplitude ntawm lub sawv nthwv dej ntawm qhov siab tshaj plaws. Cov no tshwm sim nruab nrab ntawm lub nodes.
