Kev taw qhia hluav taws xob ntau
Lub zog hluav taws xob yog hais txog qhov sib xyaw ntawm cov hluav taws xob hluav taws xob lub zog thiab kev sib nqus hluav taws xob hauv kev siv hluav taws xob, thiab tseem hu ua lub zog ntawm hluav taws xob tsis. Hnub ci hluav taws xob ntaus lub ntiaj teb ntawm qhov ceev ntawm lub teeb (c = 3 × 10 ^ 8 metres / thib ob), thiab nws muaj ob qho tib si ntawm cov yam ntxwv thiab cov nthwv dej. Hauv qhov chaw nruab ntug ntawm lub cev, kev txais tos thiab kev cia khoom ntawm lub zog radiant yog cais tsis dhau los ntawm cov yam ntxwv no. Piv txwv li, cov nroj tsuag ntsuab muaj kab loog, thiab lub zog nqus tau nqa tawm hauv daim ntawv ntawm lub teeb quanta. Vim tias qhov no quantum yam ntxwv ntawm radiant zog, qhov ntau ntawm quantum zog yog nyob ntawm yoj thiab zaus. Raws li peb txhua tus paub, lub teeb muaj ob txheej teeb meem tsis sib haum ntawm cov hluav taws xob tsis muaj hluav taws xob thiab cov quantum zog, thiab theories tshiab tau lees tias lub teeb yog qhov hluav taws xob ntawm cov khoom siv hluav taws xob nrog cov hluav taws xob zoo li qub ntawm xoom, thiab qhov kev tshaj tawm ntawm kev sib tsuam ntawm hluav taws xob nruab nrab cov khoom hluav taws xob tsis yooj yim. Ob qho hluav taws xob thiab lub tshuab hluav taws xob tau tsim tawm, tom qab ntawd cov lus piav qhia saum toj no ntawm magnetoelectricity ntawm lub hnub ci tsis sib xws nrog cov lus piav qhia ntawm cov optical quantum piav qhia tom qab.
