Suab yog ib tug longitudinal yoj uas muaj compressions thiab rarefactions taug kev los ntawm ib tug nruab nrab. Suab nthwv dej tuaj yeem piav qhia los ntawm tsib yam ntxwv : Wavelength, amplitude, Lub Sijhawm-Lub Sijhawm, Zaus thiab Velocity lossis Ceev. Qhov tsawg kawg nkaus nyob deb uas a suab wave repeats nws tus kheej yog hu ua nws wavelength.
Kuj kom paub yog, plaub yam ntxwv ntawm lub suab yog dab tsi?
Cov qualities no muaj feem xyuam rau ntau yam ntawm cov suab , xws li lub ntim lossis lub sijhawm ntev. Muaj plaub suab qualities: suab, ntev, siv thiab timbre.
Tsis tas li ntawd, cov yam ntxwv tseem ceeb ntawm lub suab yog dab tsi? Txij li thaum suab yog nthwv dej, peb tuaj yeem txheeb cov khoom ntawm suab mus rau lub zog ntawm yoj. Cov yooj yim cov khoom ntawm suab yog: suab, suab nrov thiab suab nrov. Daim duab 10.2: Pitch thiab nrov ntawm suab . Suab B muaj suab qis (tsawg zaus) dua Suab A thiab yog softer (me me amplitude) dua Suab C.
Kuj tseem paub yog, 6 tus yam ntxwv ntawm lub suab yog dab tsi?
Six Basic Properties of Suab
- Zaus / suab.
- Amplitude / Suab nrov.
- Spectrum / Timbre.
- Duration.
- Lub hnab ntawv.
- Qhov chaw.
Dab tsi yog 7 lub zog ntawm lub suab?
- 7 Yam ntxwv Ntawm Lub Suab, thiab Vim Li Cas Koj Yuav Tsum Paub Lawv. Los ntawm Reagan Ramm | Ntau lawm.
- Ntau zaus. Xav txog lub suab zoo li nthwv dej hauv dej hiav txwv ntxuav ntawm lub puam.
- Amplitude. Lwm tus yam ntxwv ntawm lub suab yog "Amplitude".
- Timbre. Thaum twg kuv pom lo lus no, kuv xav hais nws "tim-bray".
- Lub hnab ntawv.
- Ceev ceev.
- Lub wavelength.
- Theem.

Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Dab tsi yog tus yam ntxwv ntawm lub suab?
Pitch yog ib tug yam ntxwv ntawm lub suab uas ib tug raug daim ntawv yuav txawv ntawm ib tug ntxa los yog ib tug ca daim ntawv. Peb tuaj yeem txheeb xyuas tus poj niam thiab txiv neej lub suab yam tsis pom lawv. Lo lus 'pitch' feem ntau siv hauv suab paj nruag. Pitch nyob ntawm qhov zaus ntawm lub suab nthwv dej
Cov yam ntxwv ntawm cov suab puam yog dab tsi?
Cov yam ntxwv dav dav ntawm cov suab puam: Aridity: Nws yog ib qho thiab cov yam ntxwv ntawm tag nrho cov suab puam thoob plaws feem ntau lossis tag nrho lub xyoo. Qhov kub thiab txias: Humidity: Precipitation: Drought: siab cua tshaj tawm. Sparity ntawm huab npog. Tsis muaj dej vapor hauv huab cua
Peb lub neej yog dab tsi thiab lawv cov yam ntxwv tshwj xeeb yog dab tsi?
Peb lub npe suav nrog: Archaea - cov npe qub tshaj plaws, cov kab mob qub. Cov kab mob - tag nrho lwm cov kab mob uas tsis suav nrog hauv Archaea domain. Eukarya - tag nrho cov kab mob uas muaj eukaryotic los yog muaj cov kab mob sib txuas thiab cov nuclei
