Vor 4 Tagen · Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality. At all scales where measurements have been practical, matter exhibits wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave.
Vor 5 Tagen · Maxwell's equations may be combined to demonstrate how fluctuations in electromagnetic fields (waves) propagate at a constant speed in vacuum, c (299 792 458 m/s). Known as electromagnetic radiation, these waves occur at various wavelengths to produce a spectrum of radiation from radio waves to gamma rays.
2. Mai 2024 · In quantum physics, a wave function (or wavefunction) is a mathematical description of the quantum state of an isolated quantum system. The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively). Wave functions are complex-valued.
30. Apr. 2024 · In this explainer, we will learn how to calculate the de Broglie wavelength of massive particles that have a given momentum or velocity. Recall that light can be described using both a wave model and a particle model. Phenomena such as refraction and diffraction can be explained using the wave model of light.
Vor 5 Tagen · Wave-particle duality is the term for the fact that fundamental objects in the universe such as photons or electrons appear to exhibit aspects of either waves or particles depending on the experiment. Through the beginning of the twentieth century, light was widely accepted to be a wave while matter was understood to be comprised of ...
His "matter-waves" generalize Einstein's photon such that every particle we observe in the universe has the property of being both a particle and a wave. Interference and diffraction experiments performed with electrons have confirmed de Broglie's claim.
16. Apr. 2024 · Matter waves and particle beams articles from across Nature Portfolio. Latest Research and Reviews. Matter-wave collimation to picokelvin energies with scattering length and potential shape...
