Vuag tuaj nyob rau hauv ob hom, longitudinal thiab transverse. Transverse nthwv dej zoo li cov nyob hauv dej, nrog rau saum npoo av nce thiab nqis, thiab longitudinal nthwv dej yog zoo li cov suab, muaj alternating compressions thiab rarefactions nyob rau hauv ib tug nruab nrab.
Ntawm no, 4 hom nthwv dej yog dab tsi?
Ntau hom nthwv dej muaj a txawv txheej yam ntxwv. Raws li kev taw qhia ntawm particle motion thiab kev taw qhia ntawm lub zog, muaj peb pawg: Mechanical nthwv dej . Electromagnetic nthwv dej.
Electromagnetic Wave
- Microwaves.
- X-ray.
- Xov tooj cua.
- Ultraviolet yoj.
Kuj Paub, muaj pes tsawg hom nthwv dej muaj? peb hom
Yog li ntawd, Wave piav qhia li cas?
Vuag koom nrog kev thauj mus los ntawm lub zog yam tsis muaj kev thauj khoom. Hauv kev xaus, a yoj tuaj yeem piav qhia raws li kev cuam tshuam uas taug kev los ntawm qhov nruab nrab, thauj lub zog los ntawm ib qho chaw (nws qhov chaw) mus rau lwm qhov chaw yam tsis muaj teeb meem thauj.
Dab tsi yog 5 hom nthwv dej?
Hauv qab no hais yog cov ntau hom ntawm E. M nthwv dej tam sim no nyob rau hauv lub spectrum. Micro Vuag , Xov tooj cua Vuag , Infrared Rays, Ultraviolet, Pom Lub Teeb, Gamma Rays thiab X rays, yog thawj E. M. yoj ntau yam.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Dab tsi yog longitudinal waves ib hom yoj yoj rau?
Hauv cov lus yooj yooj yim, cov nthwv dej ntev yog hom nthwv dej ntawm qhov kev hloov pauv ntawm qhov nruab nrab yog nyob rau tib txoj kev uas cov nthwv dej txav mus. Qhov no txhais tau hais tias particle txav ntawm lub nthwv dej yuav sib npaug rau cov kev taw qhia ntawm lub zog txav
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Dab tsi yog qhov txawv ntawm N hom semiconductor thiab P hom semiconductor?
Hauv N-hom semiconductor, cov khoom siv hluav taws xob feem ntau yog cov neeg nqa khoom thiab qhov yog cov neeg nqa khoom tsawg. Hauv P-hom semiconductor, qhov yog feem ntau cov neeg nqa khoom thiab cov khoom siv hluav taws xob yog cov neeg tsawg. Nws muaj qhov loj dua electron concentration thiab tsawg lub qhov concentration. Nws muaj qhov loj dua qhov concentration thiab tsawg dua electron concentration
