Cov ntsiab lus yooj yim ntawm kev siv hluav taws xob
Kev Sib Tsoo Hluav Taws Xob Ib qho ntawm plaub ntawm kev sib txuam nrog xwm. Nws yog kev sib cuam tshuam ntawm cov ntawv foob thiab lub tshuab hluav taws xob thiab kev sib cuam tshuam ntawm cov khoom sib txuas tau kis los ntawm electromagnetic teb. Nws yog tus thib ob nkaus rau plaub hom kev sib txuam hauv kev siv. Kev sib txuas ntawm lub tshuab hluav taws xob thiab kev sib txuas yog lub zog sib txawv ntev uas tuaj yeem ua rau ntawm qhov kev ncua deb ntawm qhov ntsuas macroscopic thiab tshwm sim li qhov tshwm sim macroscopic. Lub macro-electromagnetic sib cuam tshuam kev tshawb xav yog sau ua ke hauv Maxwell' s sib npaug thiab tau ua haujlwm rau tib neeg txij li xyoo 19th. Microcopic electromagnetic sib cuam tshuam kev tshawb xav yog quantum electrodynamics, uas yog kev sib txuas ntawm Maxwell' s electromagnetic kev tshawb xav thiab quantum mechanical ntsiab cai.
