28 de abr. de 2024 · The American physicist Arthur Holly Compton explained (1922; published 1923) the wavelength increase by considering X-rays as composed of discrete pulses, or quanta, of electromagnetic energy. The American chemist Gilbert Lewis later coined the term photon for light quanta.

23 de abr. de 2024 · The observations of the Compton effect (1922) by American physicist Arthur Holly Compton could be explained only if light had a wave-particle duality. French physicist Louis de Broglie proposed (1924) that electrons and other discrete bits of matter, which until then had been conceived only as material particles, also have wave ...
