Kwv yees li 150 xyoo dhau los, James Clerk Maxwell James Clerk Maxwell Maxwell tau ua pov thawj tseeb, thiab nws qhov kev sib txuas ntau ntawm lub teeb thiab electromagnetism yog suav tias yog ib qho kev ua tiav zoo ntawm xyoo 19th kev lej. physics. Maxwell kuj tau qhia txog lub tswv yim ntawm electromagnetic teb nyob rau hauv kev sib piv rau cov kab uas Faraday piav. https://en.wikipedia.org › wiki › James_Clerk_Maxwell
James Clerk Maxwell - Wikipedia
, tus kws tshawb fawb Askiv, tau tsim cov kev tshawb fawb tshawb fawb los piav qhia cov nthwv dej electromagnetic. Nws pom tias cov hluav taws xob thiab cov hlau nplaum sib nqus tuaj yeem ua ke los tsim cov hluav taws xob hluav taws xob.
Leej twg tsim hluav taws xob nthwv dej ua ntej?
Michael Faraday yog thawj tus kws tshawb fawb uas tsim hluav taws xob nthwv dej hauv chav kuaj. Michael Faraday, ib lub npe uas koj yuav tau paub dhau los yog ib tus kws tshawb fawb Askiv uas tau yug los rau lub Cuaj Hli, 1971. Nws muaj npe nrov rau nws txoj kev koom tes hauv electromagnetism thiab electrochemistry.
Leej twg tsim hluav taws xob nthwv dej hauv chav kuaj?
Hertz nrhiav pom cov nyhuv photoelectric (1887) heev los ntawm kev sib tsoo thaum tsim hluav taws xob nthwv dej …….
electromagnetic nthwv dej nyob qhov twg?
Electromagnetic nthwv dej yog tsim thaum anhluav taws xob teb (uas yog pom hauv cov xub xiav) ob peb lub teb chaws sib nqus (uas pom hauv cov xub liab). Sib nqus thiab hluav taws xob teb ntawm electromagnetic yoj yog perpendicular rau ib leeg thiab rau cov kev taw qhia ntawm yoj.
Yuav ua li cas electromagnetic waves raug tsim?
Electromagnetic nthwv dej yog tsim thaum twg hluav taws xob tau nrawm. Qhov no ua rau nws muaj peev xwm tsim tau cov hluav taws xob hluav taws xob los ntawm kev cia ib qho kev hloov pauv tam sim no los ntawm cov xaim, kav hlau txais xov. Qhov zaus ntawm cov nthwv dej uas tsim los ntawm txoj kev no sib npaug ntawm qhov zaus ntawm qhov hloov pauv tam sim no.
