Vuag muaj txav crests (los yog peaks) thiab troughs . Lub crest yog qhov siab tshaj plaws qhov nruab nrab nce mus rau thiab a lub qhov yog qhov qis tshaj qhov nruab nrab dab dej rau. Crests thiab troughs ntawm transverse yoj tau pom hauv daim duab 8.2. Lub crest yog qhov taw tes ntawm lub yoj qhov twg qhov kev hloov pauv ntawm qhov nruab nrab yog qhov siab tshaj plaws.

Tsis tas li ntawd, lub kwj ntawm nthwv dej nyob qhov twg?

Qhov siab tshaj qhov saum npoo ntawm a yoj yog hu ua crest, thiab qhov qis tshaj yog qhov lub qhov . Vertical nrug ntawm lub crest thiab lub lub qhov yog cov yoj qhov siab.

Qhov thib ob, dab tsi yog lub ntsiab lus nthwv dej yooj yim? A yoj yog ib hom oscillation (kev cuam tshuam) uas taug kev los ntawm qhov chaw thiab teeb meem. Wave cov lus tsa suab hloov lub zog ntawm ib qho mus rau lwm qhov.

Hauv qhov no, dab tsi txhais tau tias hauv physics?

Trough : Trough yog ib tug taw tes nyob rau hauv lub voj voog qhov tsawg kawg nkaus amplitude muaj. Hauv lwm txoj kev, nws yog ib qho taw tes ntawm qhov tsis zoo ntawm nthwv dej uas qhov tsawg kawg nkaus amplitude tshwm sim. Daim duab 1 yog lub teeb thiab lub qhov qhia txog lub voj voog.

Dab tsi yog amplitude hauv nthwv dej?

Cov amplitude ntawm a yoj hais txog qhov siab tshaj plaws ntawm kev hloov pauv ntawm ib qho ntawm qhov nruab nrab ntawm nws qhov chaw so. Thiab qhov ntev ntawm ib qho xws li spatial repetition (lub npe hu ua a yoj cycle) yog lub wavelength. Lub wavelength tuaj yeem ntsuas raws li qhov kev ncua deb ntawm crest mus rau crest lossis los ntawm trough mus rau trough.
