Lawv tag nrho oscillate --uas yog, lawv tsiv rov qab los ntawm ob lub ntsiab lus. Ntau qhov system oscillate , thiab lawv muaj tej yam ntxwv hauv feem ntau . Tag nrho oscillations koom nrog lub zog thiab lub zog. Ib txhia oscillations tsim nthwv dej.
Ntawm no, kev sib raug zoo ntawm oscillations thiab nthwv dej yog dab tsi?
Thaum a yoj (xav tias suab yoj ) propagate los ntawm ib tug nruab nrab ces cov hais ntawm nruab nrab pib vibrating, qhov no vibration hu ua oscillation thiab nws mus dhau ntawm ib qho kev taw qhia, uas yog hu ua yoj (kev cuam tshuam nyob rau hauv nruab nrab sib law liag nyob rau hauv ib tug meej kev taw qhia).
Tom qab ntawd, lo lus nug yog, dab tsi yog ib qho oscillation ntawm nthwv dej? Oscillation yog qhov kev hloov pauv rov ua dua, feem ntau hauv lub sijhawm, ntawm qee qhov kev ntsuas txog tus nqi nruab nrab (feem ntau yog qhov sib npaug) lossis ntawm ob lossis ntau lub xeev sib txawv. Lub sij hawm vibration yog precisely siv los piav txog txhua yam oscillation.
Ua li no, txhua hom nthwv dej muaj dab tsi?
Cov nthwv dej sib txawv, tib lub zog Cov no suav nrog suab nthwv dej, lub teeb nthwv dej, xov tooj cua nthwv dej, microwaves thiab lwm yam. Txhua hom nthwv dej muaj tib lub ntsiab lus ntawm kev xav, refraction , diffraction thiab cuam tshuam, thiab tag nrho cov nthwv dej muaj lub wavelength, zaus, ceev thiab amplitude.
Lub suab thiab electromagnetic tsis muaj dab tsi sib xws?
A Suab nthwv dej yog ib tug longitudinal wave whereas, electromagnetic tsis yog transverse nthwv dej . EMR yog ib hom ntawm lub zog uas tawm thiab nqus los ntawm cov khoom siv hluav taws xob. Suab tsis xav tau nruab nrab mus ncig tab sis electromagnetic yoj ua tsis yog xav tau ib qho nruab nrab mus ncig. Electromagnetic tsis txav nrog ceev heev hauv lub tshuab nqus tsev.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Dab tsi yog electromagnetic nthwv dej tag nrho muaj sib xws?
Lawv txhua tus muaj cov khoom sib xws. Hauv lub tshuab nqus tsev, lawv txhua tus taug kev ntawm tib qhov ceev - qhov ceev ntawm lub teeb - uas yog 3 × 108 m / s. Lawv yog cov transverse nthwv dej, nrog cov oscillations yog hluav taws xob thiab magnetic teb. Zoo li tag nrho cov nthwv dej, lawv tuaj yeem cuam tshuam, refracted thiab diffraction
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Dab tsi yog qhov sib txawv ntawm kev sib tw thiab cov lej sib xws?
Peb siv cov lej sib xws los ua kom qhov teeb meem yooj yim dua los daws hauv peb lub taub hau los ntawm kev hloov txhua tus lej mus rau qhov ze tshaj kaum, nees nkaum, tsib caug lossis puas. Tab sis yog tias peb ua cov lej sib xws thiab sib npaug mus rau qhov ze tshaj plaws puas lossis kaum qhov chaw, 300 thiab 350 yog qhov yooj yim dua los suav hauv peb lub taub hau
