de broglie matter waves

The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be po..

Under certain experimental conditions, a beam of particles (for example, electrons ) can exhibit wavelike properties. Such matter waves are governed by the laws of quantum physics. The wavelength is inversely proportional to the momentum of the particles. These are also known a..

; in other words, these waves can pass through vacuum They require medium for propagation i.e. these waves cannot pass through vacuum All electromagnetic waves travel with the same velocity Matter waves travel with different velocities The velocity ..

De-Broglie noted that according to the theory of relativity, the role played by momentum 'P' and the energy 'E' of the particle is done by angular frequency ' w ' and the propagation vector 'k' of a wave. According to Einstein relation E = mc 2 Where 'm' is the mass of the p..

>Thus, the wavelength of material particles, l is: This equation is known as de-Broglie's equation. where p stands for the momentum (mv) of the particle. Since h is constant, l 1/Momentum. It means that the wavelength of a particle in motion is inversely proportional to its momentum. The ..

The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h n .....(1) According to Einstein, mass and energy are related as: E = mc 2..

Very often, energy is generated at one place but consumed elsewhere. The transportation of energy from its source to the receiving end can be done in two ways: By actually moving the matter carrying kinetic energy and delivering it to the other en..

. have also dual character. In other words, the microscopic particles in motion possess both the particle and wave characteristics. Thus, according to de-Broglie, "all material particles in motion possess wave characteristics". According to de-Broglie, the wa..
