particles that behave like waves.

particles behave like waves.

De Broglie was the question of whether it is possible that the particles have wave properties?

suggested that all _electrones particles, atoms, protons, etc.-have a wavelength related to its momentum according to the equation ...

Length wave = Planck's constant : momentum

The wavelength of a particle of large mass and low speed is too small to be able to detect by conventional means. But a small particle like an electron moving with speed has a wavelength detectable. Is smaller than the wavelength of light, but enough to diffract and cross interference, since a beam of electrons acts as a beam of light.

The typical wavelength of an electron beam is thousands of times smaller than that of light, and can only be detected by electron microscopy.

electron waves

Much more important than the electron diffraction pattern is the de Broglie matter waves in an atom. The atomic model of Niels Bohr, explaining why elements emit light of certain frequencies. The power of e-varies according to the orbits they occupy.

There are several ways of getting a e-access to higher energy levels. Returning to his level of stability emits a photon.

wanted to explain is that in the solar system each planet revolves in orbit at any distance, and conversely in the atom are orbits in which the e-must turn. This was because it was assumed that e-was a particle that orbits around the nucleus.

The reason that the electron can only occupy certain places understood by considering the electron as a particle, but as a wave. According to the theory of de Broglie matter waves, an orbit can exist where the electron OUNTY closes on itself in phase. This will reinforce itself. From this point of view, the electron is not considered as a particle located somewhere in the atom, but as if their mass and charge were spread over a wave around the nucleus. The wavelength of the e-must fit an integral number of times in the orbits.
