Electromagnetic tsis txawv ntawm mechanical nthwv dej hauv lawv tsis xav tau a nruab nrab mus tshaj tawm. Qhov no txhais tau tias electromagnetic tsis ua tau tsis mus tsuas yog los ntawm huab cua thiab cov khoom siv, tab sis kuj los ntawm lub tshuab nqus tsev. Qhov no ua pov thawj tias xov tooj cua vuag tau ib lub teeb!
Tsis tas li ntawd, vim li cas electromagnetic nthwv dej tsis xav tau qhov nruab nrab rau kev mus ncig?
EM - nthwv dej tsis xav tau qhov nruab nrab vim lawv yog TSIS yoj zoo ib yam li dej nthwv dej lub suab nthwv dej.
Tsis tas li ntawd, vim li cas electromagnetic nthwv dej hla dhau lub tshuab nqus tsev? Electromagnetic tsis yog nthwv dej uas tuaj yeem hla dhau tus lub tshuab nqus tsev ntawm qhov chaw sab nrauv. Electromagnetic tsis yog tsim los ntawm kev vibration ntawm tus nqi hluav taws xob. Qhov kev vibration no tsim ib yoj uas muaj ob qho tib si hluav taws xob thiab cov khoom sib nqus.
Xav txog qhov no, vim li cas nthwv dej xav tau qhov nruab nrab mus ncig?
Neeg kho tshuab nthwv dej yog nthwv dej uas xav tau a nruab nrab . Qhov no txhais tau tias lawv yuav tsum muaj qee yam teeb meem taug kev dhau. Cov no vuag ncig thaum cov molecules nyob rau hauv lub nruab nrab sib tsoo nrog ib leeg dhau ntawm lub zog.
Yam nthwv dej twg yuav tsum muaj cov khoom nruab nrab los ntawm kev mus ncig?
Neeg kho tshuab Vuag : Qhov no hom yoj yuav tsum tau a nruab nrab ( khoom ) rau taug kev los ntawm . Piv txwv li nthwv dej yuav yog nthwv dej ntawm ib txoj hlua dhia, slinky, nto nthwv dej ntawm dej, thiab suab nthwv dej . 2.

Vim li cas cov nthwv dej transverse tsim los ntawm av qeeg hu ua cov nthwv dej thib ob?
Secondary waves (S-waves) yog shear waves uas yog transverse nyob rau hauv cov xwm. Tom qab muaj xwm txheej av qeeg, S-nthwv dej tuaj txog ntawm cov chaw nres tsheb seismograph tom qab nrawm dua-tsav P-nthwv dej thiab hloov chaw hauv av perpendicular mus rau kev taw qhia ntawm kev nthuav tawm
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
Lub suab nthwv dej taug kev hauv huab cua nruab nrab piav qhia li cas?
Lub suab nthwv dej taug kev los ntawm huab cua tiag tiag yog cov kab ntev ntev nrog compressions thiab tsis tshua muaj. Raws li lub suab dhau los ntawm huab cua (lossis ib qho nruab nrab ntawm cov kua dej), cov khoom ntawm huab cua tsis vibrate nyob rau hauv ib tug transverse yam. Kev piav qhia: Cov kev vibrations dhia ntawm ib qho mus rau lwm qhov
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
