Zuag qhia tag nrho tiv thaiv hluav taws xob hluav taws xob hauv cheeb tsam tam sim
Qhov tshwm sim ntawm hluav taws xob hluav taws xob yog hais txog kev puas tsuaj tshwm sim rau tib neeg lub cev thiab cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv hluav taws xob los ntawm cov hluav taws xob hluav taws xob uas tsim los ntawm cov khoom siv hluav taws xob loj. Ntuj electromagnetic hluav taws xob los ntawm lub ntiaj teb thermal hluav taws xob, hnub ci thermal hluav taws xob, cosmic rays, thiab hluav taws xob zoo li qub; Cov hluav taws xob hluav taws xob hluav taws xob muaj ntau qhov chaw, suav nrog kev ua haujlwm ntawm cov kab hluav taws xob hluav taws xob, cov chaw siv hluav taws xob, cov chaw nres tsheb, xov tooj cua, cov cuab yeej hluav taws xob, cov cuab yeej siv kho mob, cov khoom siv laser, thiab cov khoom siv hauv chaw ua haujlwm, nrog rau kev siv cov khoom siv hauv tsev xws li microwave. qhov cub, TV, xov tooj ntawm tes, cua txias, pam hluav taws xob, thiab xov tooj cua.
Cov hluav taws xob hluav taws xob hluav taws xob feem ntau muab faib ua ze- teb thiab thaj tsam deb. Lub cheeb tsam nyob ib ncig ntawm lub teb qhov chaw nyob rau hauv ib tug wavelength ntau yam yog feem ntau hu ua lub ze-tsav; Ntawm qhov tsis sib xws, thaj av sab nraud ntawm ib lub wavelength ntau yog feem ntau hu ua qhov chaw deb. Ob hom kev teb muaj cov yam ntxwv sib txawv: nyob rau hauv qhov chaw ze, tsis muaj qhov sib npaug sib luag ntawm lub zog hluav taws xob thiab lub zog sib nqus. Feem ntau, rau thaj chaw uas muaj qhov hluav taws xob siab thiab tsis tshua muaj tam sim no, xws li xa cov kav hlau txais xov, feeders, thiab lwm yam, cov hluav taws xob hluav taws xob muaj zog ntau dua li cov hlau nplaum; Rau qhov tsis tshua muaj hluav taws xob thiab qhov chaw siab tam sim no, xws li cov khoom siv hluav taws xob induction cua sov, qhov chaw sib nqus yog qhov loj dua qhov hluav taws xob. Nyob rau hauv qhov chaw deb, tag nrho cov hluav taws xob hluav taws xob hluav taws xob yog hluav taws xob thiab nthuav tawm hauv daim ntawv ntawm cov hluav taws xob hluav taws xob, thiab qhov txo qis ntawm cov hluav taws xob siv hluav taws xob hauv daim teb no qeeb dua li hauv qhov induction teb. Nyob rau hauv qhov deb, lub zog hluav taws xob thiab hlau nplaum muaj kev sib raug zoo hauv qab no: E=377H, kev taw qhia ntawm cov hluav taws xob thiab cov hlau nplaum sib nqus yog qhov sib npaug rau ib leeg, thiab ob qho tib si yog perpendicular rau cov kev taw qhia ntawm electromagnetic yoj propagation. . Qhov chaw deb yog qhov chaw tsis muaj zog, thiab nws lub zog electromagnetic yog qhov me me.
Lub tshuab hluav taws xob hluav taws xob siv hluav taws xob nyob ze ntawm thaj chaw ze yog ntau dua li qhov nyob deb, thiab hluav taws xob hluav taws xob feem ntau cuam tshuam thiab ua rau tib neeg lub cev puas tsuaj hauv thaj tsam ze. Kab lus no npaj siab muab qee cov tswv yim thiab cov kev coj ua rau tag nrho kev tiv thaiv kev tiv thaiv hluav taws xob hluav taws xob tiv thaiv hluav taws xob nyob ib puag ncig ntawm qhov chaw.
