Qhov siab tshaj plaws ntawm nthwv dej yog hu ua crest, thiab qhov qis tshaj plaws yog lub qhov. Qhov kev ncua deb ntawm lub crest thiab trough yog 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.

Koj pom qhov kev ncua deb ntawm ob lub crest li cas?

Raisoning Qhov kev ncua deb ntawm cov crests uas nyob ib sab yog lub wavelength l Vim qhov ceev ntawm txhua nthwv dej yog v=3.00 × 10 8 m/ s thiab cov frequencies tau paub, qhov kev sib raug zoo v=fl tuaj yeem siv los txiav txim siab lub wavelengths. Qhov sib npaug v=fl siv rau txhua yam ntawm lub sijhawm yoj.

qhov kev ncua deb ntawm lub crest mus rau crest hu li cas?

Lub wavelength tuaj yeem ntsuas tau raws li qhov kev ncua deb ntawm crest mus crest lossis los ntawm trough mus rau trough.

Qhov kev ncua deb ntawm ob lub ncov lossis crest yog dab tsi?

wavelength| Qhov kev ncua deb ntawm ib lub ncov los yog crest ntawm ib tug nthwv dej ntawm lub teeb, tshav kub, los yog lwm yam zog thiab lub tom ntej no ncov los yog crest. amplitude | Qhov siab ntawm lub crest (los yog qhov tob ntawm ib lub qhov) ntawm nthwv dej.

Qhov chaw nruab nrab ntawm nthwv dej hu ua dab tsi?

Qhov kev ncua deb ntawm ob qho kev ua tiav yog hu ua lub wavelength. Nws yog tib yam li qhov kev ncua deb ntawm ob qho tib si troughs. Qhov tseeb, qhov kev ncua deb ntawm tib lub ntsiab lus ntawm ib qho kev sib txuas ntawm ob lub wavelength yog tib qhov deb li qhov wavelength.
