~ Electromagnetic tsis txav tus ceev tshaj plaws los ntawm cov pa roj. Txij li thaum electromagnetic vuag ua tsis xav tau ib qho nruab nrab los ntawm, lawv yog sai dua nyob rau hauv cov teeb meem uas muaj tsawg hais. Cov particles nyob rau hauv gases yog ntau kis tawm tshaj cov khoom hauv cov khoom khib nyiab lossis hauv cov kua, yog li electromagnetic nthwv dej txav ceev ceev los ntawm cov pa roj.

Ntxiv mus, qhov twg electromagnetic tsis txav qeeb tshaj plaws?

Neeg kho tshuab nthwv dej - taug kev sai dua hauv cov khoom khov & qeeb tshaj plaws hauv gases 2. Electromagnetic tsis - taug kev ceev tshaj plaws hauv qhov chaw khoob thiab qeeb tshaj plaws hauv cov khoom khov.

Tom qab ntawd, lo lus nug yog, cov khoom siv hluav taws xob puas tuaj yeem txav tau? Electromagnetic tsis txawv ntawm mechanical nthwv dej hauv lawv ua tsis xav tau qhov nruab nrab los nthuav tawm. Qhov no txhais tau tias electromagnetic tsis tuaj yeem taug kev tsis tsuas yog los ntawm huab cua thiab cov khoom siv, tab sis kuj los ntawm lub tshuab nqus tsev.

Ib yam li ntawd, tib neeg nug, ua li cas electromagnetic nthwv dej taug kev?

Electromagnetic tsis yog nthwv dej uas tuaj yeem taug kev los ntawm lub tshuab nqus tsev ntawm qhov chaw sab nraud. Qhov kev vibration no tsim ib yoj uas muaj ob qho tib si hluav taws xob thiab cov khoom sib nqus. Ib electromagnetic yoj thauj nws lub zog los ntawm lub tshuab nqus tsev ntawm qhov ceev ntawm 3.00 x 108 m / s (tus nqi nrawm feem ntau sawv cev los ntawm lub cim c).

Dab tsi electromagnetic nthwv dej muaj qhov luv tshaj wavelength thiab lub siab tshaj plaws nthwv dej?

Gamma rays muaj lub zog siab tshaj plaws, qhov luv tshaj wavelengths, thiab lub siab tshaj plaws frequencies. Cov xov tooj cua tsis muaj zog, ntawm qhov tod tes, muaj lub zog qis tshaj, qhov ntev tshaj plaws wavelengths, thiab qis tshaj zaus ntawm txhua hom EM hluav taws xob.
