Suab nrov yog cov piv txwv ntawm mechanical nthwv dej thaum lub teeb nthwv dej yog cov piv txwv ntawm electromagnetic tsis . Electromagnetic tsis yog tsim los ntawm kev vibration ntawm hluav taws xob. Qhov no vibration tsim ib yoj uas muaj ob qho tib si hluav taws xob thiab magneticcomponent.
Ua raws li qhov no saib, vim li cas lub suab yog electromagnetic yoj?
Electromagnetic hluav taws xob yog qhov kev nthuav tawm los ntawm qhov chaw ntawm hluav taws xob thiab hlau nplaum nthwv dej thaum suab yog qhov tshwm sim ntawm kev hloov me me hauv huab cua siab uas nthuav tawm los ntawm huab cua. Qee zaum peb tuaj yeem pom electromagnetic tawg (raws li lub teeb) los yog hnov nws (zoo li sov so) thaum peb tsuas hnov suab.
Ib tug kuj yuav nug, ua li cas lub suab thiab electromagnetic nthwv dej zoo sib xws? Suab nrov yog longitudinal nthwv dej uas yog, kis nyob rau hauv tib yam kev taw qhia ntawm oscillation ntawm cov hais nyob rau hauv nruab nrab. Electromagnetic tsis yog transverse piv txwv li, hluav taws xob thiab magnetic teb, uas yog perpendicular rau ib leeg, oscillate perpendicularly rau txoj kev ntawm yoj kev nthuav tawm.
Xav txog qhov no, puas yog suab EM nthwv dej yog tias tsis yog hom nthwv dej zoo li cas?
Tsis yog, suab yog tsis yog ib electromagnetic wave . Suab yog longitudinal mechanical (siab) yoj , uas yuav tsum tau ib tug nruab nrab nyob rau hauv uas mus ncig teb chaws. Qhov nruab nrab tuaj yeem yog roj, kua, lossis khoom. EM vuag ua tsis yog xav tau ib qho nruab nrab uas mus ncig.
Electromagnetic yoj ua li cas?
Ib electromagnetic yoj tuaj yeem tsim los ntawm kev them nqi nrawm; tsiv cov nqi rov qab thiab rov qab yuav tsim tawm oscillating hluav taws xob thiab magnetic teb, thiab thesetravel ntawm qhov ceev ntawm lub teeb.

Yuav ua li cas koj xam lub zog ntawm ib tug electromagnetic yoj?
Lub zog nqa los ntawm ib qho yoj yog proportional rau nws amplitude squared. Rau electromagnetic nthwv dej, qhov no txhais tau hais tias siv tau raws li Iave = cϵ0E202 I ave = c ϵ 0 E 0 2 2, qhov twg Iave yog qhov nruab nrab siv nyob rau hauv W / m2, thiab E0 yog qhov siab tshaj plaws hluav taws xob teb lub zog ntawm lub nruam sinusoidal yoj
Puas yog tag nrho cov electromagnetic tsis muaj qhov ceev tib yam hauv lub tshuab nqus tsev?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
Qhov twg electromagnetic yoj muaj qhov luv tshaj wavelength thiab siab tshaj plaws zaus?
Gamma rays muaj lub zog siab tshaj plaws, qhov luv tshaj wavelengths, thiab cov zaus siab tshaj plaws. Cov xov tooj cua tsis muaj zog, ntawm qhov tod tes, muaj lub zog qis tshaj plaws, qhov ntev tshaj plaws wavelengths, thiab qis tshaj zaus ntawm txhua hom EM hluav taws xob
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
Qhov twg electromagnetic yoj muaj zog tshaj?
Txhua ntu ntawm electromagnetic (EM) spectrum muaj cov yam ntxwv ntawm lub zog, wavelengths, thiab frequencies txuam nrog nws cov photons. Gamma rays muaj qhov siab tshaj plaws, qhov luv tshaj wavelengths, thiab qhov siab tshaj plaws
