de broglie hypothesis pdf

The Davisson–Germer experiment was a 1923-27 experiment by Clinton Davisson and Lester Germer at Western Electric (later Bell Labs), in which electrons, scattered by the surface of a crystal of nickel metal, displayed a diffraction pattern. De Broglie Hypothesis.

Louis Victor Pierre Raymond de Broglie, 7th duc de Broglie (/ d ə ˈ b r oʊ ɡ l i /, also US: / d ə b r oʊ ˈ ɡ l iː, d ə ˈ b r ɔɪ /, French: or (); 15 August 1892 – 19 March 1987) was a French physicist who made groundbreaking contributions to quantum theory.In his 1924 PhD thesis, he postulated the wave nature of electrons and suggested that all matter has wave properties. The particle behavior of matter is obvious. In quantum mechanics, matter is believed to behave both like a particle and a wave at the sub-microscopic level. In 1924, Louis de Broglie proposed a new speculative hypothesis that electrons and other particles of matter can behave like waves.

Compton’s formula established that an electromagnetic wave can behave like a particle of light when interacting with matter. After Albert Einstein's photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wave-like behavior. The De Broglie hypothesis proposes that all matter exhibits wave-like properties and relates the observed wavelength of matter to its momentum. Here is how the De Broglie hypothesis was developed.
