Double click anywhere & add an idea In anii 1923-1924, Louis de Broglie a emis urmatoarea ipoteza: ipoteza Dualismul intre unde si particule este un fenomen general in natura consecinta Pentru prima data au fost atribuite calitati ondulatorii particulelor elementare Proprietatile undelor de Broglie asociate unei particule de masa m si viteza v Conditii de cuantificare a orbitelor atomului de H. In cazul miscarii circulare momentul cinetic este: Lucrarile de interferenta si difractie a electronilor obtin rezultate asemanatoare cu cele date de studiul razelor X. Astfel, lungimea de unda de Broglie a unor electroni accelerati sub o diferenta de potential V se obtine: metoda Bragg Confirmarea
experimentala relatia Bragg metoda Davisson si Germer Ipoteza
