Hluav taws xob yog txheej txheej ntawm lub cev tshwm sim cuam tshuam nrog qhov muaj thiab kev txav ntawm cov teeb meem uas muaj cov khoom siv hluav taws xob. Hluav taws xob muaj feem xyuam rau cov hlau nplaum, ob qho tib si yog ib feem ntawm qhov tshwm sim ntawm electromagnetism, raws li tau piav los ntawm Maxwell qhov sib npaug.
Leej twg yog thawj zaug nrhiav tau hluav taws xob?
Nws ua li cas los xij, yuav tsum tau tshawb pom thiab nkag siab. Cov neeg feem coob muab credit rau Benjamin Franklin rau kev nrhiav hluav taws xob. Benjamin Franklin muaj ib lub siab zoo tshaj plaws ntawm nws lub sijhawm. Nws txaus siab rau ntau yam kev tshawb fawb, ua ntau qhov kev tshawb pom, thiab tsim ntau yam, suav nrog cov iav bifocal.
Leej twg tsim hluav taws xob ua ntej Benjamin Franklin?
Kev kawm thaum ntxov hauv hluav taws xob
Kev sim nrog hluav taws xob thiab hlau nplaum tau ua thawj zaug hauv lub sijhawm qub. Txawm li cas los xij, tus tsim ntawm kev tshawb fawb niaj hnub ntawm hluav taws xob yog William Gilbert, tus kws kho mob Askiv xyoo pua 17th. Gilbert yog thawj tus los qhia lub ntsiab lus hluav taws xob.
Thaum twg hluav taws xob pom thiab siv?
1879: Tom qab ntau qhov kev sim, Thomas Edison (Tebchaws Asmeskas) tau tsim lub teeb pom kev zoo uas tuaj yeem siv li 40 teev yam tsis tau hlawv. Los ntawm 1880 nws cov qij siv tau rau 1200 teev.
Thaum twg hluav taws xob tau tsim?
Thomas Edison
Txij li pua xyoo tom ntej no, ntau tus neeg tsim khoom thiab cov kws tshawb fawb tau sim nrhiav txoj hauv kev siv hluav taws xob los ua lub teeb. Hauv 1879, tus neeg tsim khoom Asmeskas Thomas Edison thaum kawg tuaj yeem tsim lub teeb pom kev zoo, siv tau ntev hauv nws chav kuaj.
