Second,in1905,thedevelopmentofyoungEinsteinPlanckquantum.Hebelievesthatelectromagneticradiationisaessentiallyanon-continuous,bothinatomicemissionandabsorptionoftheirtime,orinthedisseminationprocessthis.TheenergyoftheproductofthePlanck''sconstantandthefrequencyofelectromagneticradiation,E=hv.[3]
OneS=e×Hisaunittimeflowingthroughtheunitareaof??theelectromagneticenergyintheverticalplane;IIrepresentedbyE=hvistheenergyofanelectromagneticwave,orthatthetotalenergyoftheelectromagneticwavesofacertaintime.IIE=hvS=E×H?IfS=E=hv,Whatdoesitmean?WhereinEandHdenotetheaverageperiodoftheelectromagneticwaveelectricfieldstrengthandmagneticfieldstrength.WhenS=E,wastheE×H=hv=1/?E?B.Thus,weconcludedthatifthefrequencyoftheelectromagneticwavechanges,thentheaverageelectricfieldstrengthoftheelectromagneticwaveandtheaveragemagneticinductionchanges.Electromagneticfrequencybecomeslarge,thentheaverageelectricfieldstrengthandtheaveragemagneticinductionoftheelectromagneticwavestrengthbecomeslarger;Conversely,theelectromagneticwavefrequencyissmaller,thentheaverageelectricfieldstrengthandtheaveragemagneticinductionoftheelectromagneticwavestrengthbecomessmall.
Ifthelightsourcemovementorobservermovement,thenthelighthaveanyeffect?Themovementcanmakethereceivingfrequencyoftheobserverchange.Basedontheobtained,thelightsourceorthemovementoftheobservercanmaketheaverageelectricfieldstrengthoftheelectromagneticwaveandtheaveragemagneticinductionintensitychange.I.e.,sothattheelectricfieldintensityofthelightchanges,sothatthemagneticinductionintensityofthelightchanges.
Thenthelightsourceorthemovementoftheobserversothattheelectricfieldintensityofthelighttochange,accordingtoD=εEderivedE=D/ε.Thelightsourceconstant,canbeconsideredastheDunchanged,thereforeconcludethat:theelectricfieldintensitychangeispermittivitychanges.
Thecapacitanceratioisunchanged,sothelightsourceorthemovementoftheobserverisequivalenttothemediumorvacuumpermittivitychange.
Similarly,themagneticinductionintensityofthelightsourceorthemotionoftheobserversothatthelightchanges,accordingtoB=?H,thelightsourceremainsunchanged,thatHunchanged,thereforeconcludethat:thechangeinintensityofthemagneticinductionisbecausethemagneticpermeabilityoccurredchanges.Themagneticpermeabilityisgenerallyconstant,andsothelightsourceorthemovementoftheobserverisequivalenttothemediumorvacuummagneticpermeabilitychanges.
Socometotheconclusion,thelightsourceorthemovementoftheobserver,theequivalentchangeinthemediumorvacuumpermeabilityandpermittivity.
Thatisaccordingtothemovementofthelightsourceortheobserver,thentheobserver,accordingtoobtainedthespeedoflightchanges.Invacuo,andiftheobserverandthelightsourcerelativemotionoccurs,thespeedoflightwillchange.
Usuallywecometotheconclusionthattheconstantspeedoflightinavacuumisthestaticconditionsofthelightsourceandtheobserver.
Also,inadifferentmediumspeedoflightmaybedifferent,accordingtotheformulaE=hvtoo,theenergyofthelightdoesnotchange;accordingtoB=?H,D=εEobtained,EandBarechanged,accordingtoS=1/?E?B,drawenergychanges.Sodifferentmediumcorrespondingtodifferentvalues??ofh.relatedtothecapacitanceratioofthevalueofhandthemediumandthemagneticpermeabilityofthemedium.Inthepreviousarticle,weguessthevalueofhmayberelatedtothechargeofelectricity[4],thevalueofhpermittivity,permeabilitymayberelatedtotheelectronicpower.
