  2. Momentum transfer - Wikipedia

    en.wikipedia.org/wiki/Momentum_transfer

    The momentum transfer plays an important role in the evaluation of neutron, X-ray, and electron diffraction for the investigation of condensed matter. Laue-Bragg diffraction occurs on the atomic crystal lattice, conserves the wave energy and thus is called elastic scattering, where the wave numbers final and incident particles, and , respectively, are equal and just the direction changes by a ...

  3. Wave - Wikipedia

    en.wikipedia.org/wiki/Wave

    Mechanical and electromagnetic waves transfer energy, [1] momentum, and information, but they do not transfer particles in the medium. In mathematics and electronics waves are studied as signals. [2] On the other hand, some waves have envelopes which do not move at all such as standing waves (which are fundamental to music) and hydraulic jumps.

  4. Matter wave - Wikipedia

    en.wikipedia.org/wiki/Matter_wave

    The concept that matter behaves like a wave was proposed by French physicist Louis de Broglie (/ d ə ˈ b r ɔɪ /) in 1924, and so matter waves are also known as de Broglie waves. The de Broglie wavelength is the wavelength , λ , associated with a particle with momentum p through the Planck constant , h : λ = h p . {\displaystyle \lambda ...

  5. Radiation pressure - Wikipedia

    en.wikipedia.org/wiki/Radiation_pressure

    Due to the law of conservation of momentum, any change in the total momentum of the waves or photons must involve an equal and opposite change in the momentum of the matter it interacted with (Newton's third law of motion), as is illustrated in the accompanying figure for the case of light being perfectly reflected by a surface. This transfer ...

  6. Electromagnetic radiation - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation

    Electromagnetic waves are emitted by electrically charged particles undergoing acceleration, [5] [6] and these waves can subsequently interact with other charged particles, exerting force on them. EM waves carry energy, momentum, and angular momentum away from their source particle and can impart those quantities to matter with which they ...

  8. Dispersion relation - Wikipedia

    en.wikipedia.org/wiki/Dispersion_relation

    The top electron has twice the momentum, while the bottom electron has half. Note that as the momentum increases, the phase velocity decreases down to c, whereas the group velocity increases up to c, until the wave packet and its phase maxima move together near the speed of light, whereas the wavelength continues to decrease without bound. Both ...
