“For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.” LightFormCertainConditionsWaveFamiliarCharacteristicsLengthChemicalsAtomsElectricQuantumFrequencyOscillationElectromagnetic WavesLight Waves Author:Johannes Stark
“By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms.” GivingCertainFieldsAllowingAtomsElectricVelocityStationaryIons Author:Johannes Stark
