Qhov sib txawv tseem ceeb ntawm electromagnetic nthwv dej thiab teeb meem nthwv dej yog qhov hluav taws xob tsis muaj hluav taws xob muaj hluav taws xob thiab cov hlau nplaum sib txuas nrog lawv, qhov teeb meem tsis muaj hluav taws xob lossis hluav taws xob sib nqus.
Wave yog qhov cuam tshuam ntawm thaj chaw uas lub cev tus cwj pwm oscillates ntau zaus ntawm txhua qhov chaw lossis nthuav tawm los ntawm txhua qhov taw tes mus rau cov ntsiab lus nyob sib ze. Electromagnetic nthwv dej thiab teeb meem tsis yog ob hom nthwv dej li no. Tsis tas li ntawd, txhua yam teeb meem tuaj yeem coj tus cwj pwm zoo li nthwv dej. Thiab, lub tswv yim no yog thawj zaug los ntawm Louis De Broglie, uas tau coj mus rau npe cov nthwv dej no ua "Broglie nthwv dej" thiab.
Electromagnetic Wave yog dab tsi?
Ib lub nthwv dej electromagnetic yog ib hom nthwv dej uas taug kev los ntawm qhov chaw, nqa hluav taws xob hluav taws xob hluav taws xob. Cov nthwv dej no nthuav tawm ntawm qhov nrawm ntawm lub teeb hauv lub tshuab nqus tsev. Hom hluav taws xob nthwv dej muaj xws li xov tooj cua nthwv dej, microwaves, infrared rays, pom lub teeb, UV rays, thiab lwm yam. Tsis tas li ntawd, peb tuaj yeem ua tus yam ntxwv ntawm cov hluav taws xob hluav taws xob siv wavelength, zaus lossis lub zog.
Daim duab 01: Ib qho hluav taws xob hluav taws xob uas qhia txog cov hluav taws xob thiab cov hlau nplaum sib nqus
Cov kab hluav taws xob hluav taws xob no muaj ob qho hluav taws xob thiab cov khoom sib nqus. Ntawm no, peb tuaj yeem pom cov oscillation ntawm hluav taws xob thiab cov hlau nplaum sib nqus ua rau ib leeg thiab oscillates nyob rau hauv kev coj ntawm kev nthuav tawm ntawm nthwv dej.
Ntxiv mus, ib qho hluav taws xob nthwv dej muaj cov quanta hu ua "photons". Lub photon tsis muaj huab hwm coj tab sis muaj qhov sib npaug; Yog li, lub ntiajteb txawj nqus tuaj yeem cuam tshuam cov photons ib yam li cov teeb meem qub. Thaum peb muab lub zog rau ib lub atom, cov electrons tuaj yeem txav mus rau qib siab zog, tab sis vim tias lub zog siab dua lub xeev tsis ruaj khov, cov electrons poob rov qab mus rau qis zog lub xeev, tso photons. Yog li, qhov xwm txheej no tuaj yeem tsim hluav taws xob electromagnetic. Siv lub hauv paus ntsiab lus no, peb tuaj yeem tau txais emission spectra rau cov tshuaj lom neeg thiab txiav txim siab lub zog ntawm cov atoms.
Dab tsi yog qhov Wave?
Cov nthwv dej yog cov nthwv dej uas muaj cov khoom. Txawm li cas los xij, cov nthwv dej no tsis cuam tshuam nrog hluav taws xob thiab hlau nplaum. Tsis zoo li electromagnetic nthwv dej, cov teeb meem nthwv dej no muaj cov khoom (uas muaj qhov loj thiab ntim). Yog li, txhua yam teeb meem tuaj yeem coj tus yoj.
Daim duab 02: Ua qauv qhia ntawm qhov teeb meem ntawm qhov sib txawv ntawm cov hluav taws xob
Qhov teeb meem nthwv dej lub tswv yim yog thawj zaug los ntawm Louis De Broglie, uas ua rau lub npe nthwv dej no ua "Broglie nthwv dej" ib yam nkaus.
Qhov txawv ntawm Electromagnetic Wave thiab Matter Wave yog dab tsi?
Electromagnetic nthwv dej yog ib hom nthwv dej uas taug kev los ntawm qhov chaw, nqa hluav taws xob hluav taws xob hluav taws xob thaum lub teeb meem nthwv dej yog nthwv dej uas muaj cov khoom. Yog li, qhov sib txawv tseem ceeb ntawm electromagnetic yoj thiab teeb meem nthwv dej yog qhov hluav taws xob tsis muaj hluav taws xob muaj hluav taws xob thiab sib nqus teb nrog lawv, qhov teeb meem tsis muaj hluav taws xob lossis sib nqus teb.
Ntxiv mus, raws li lwm qhov sib txawv tseem ceeb ntawm electromagnetic yoj thiab teeb meem nthwv dej, peb tuaj yeem hais tias electromagnetic yoj muaj photons (uas tsis muaj huab hwm coj lossis ntim), thaum qhov teeb meem nthwv dej muaj cov khoom (uas muaj huab hwm coj thiab ntim).
Cov ntaub ntawv hauv qab no-daim duab qhia ntau qhov sib piv ntsig txog qhov sib txawv ntawm electromagnetic yoj thiab teeb meem nthwv dej.
Summary – Electromagnetic Wave vs Matter Wave
Electromagnetic nthwv dej thiab teeb meem nthwv dej sib txawv ntawm ob peb txoj hauv kev. Qhov sib txawv tseem ceeb ntawm electromagnetic yoj thiab teeb meem nthwv dej yog qhov hluav taws xob tsis muaj hluav taws xob muaj hluav taws xob thiab sib nqus teb nrog lawv (uas tau ua rau lub npe nthwv dej li no), qhov teeb meem tsis muaj hluav taws xob lossis sib nqus teb.
