Vor einem Tag · 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 · The Planck constant, or Planck's constant, denoted by , [1] is a fundamental physical constant [1] of foundational importance in quantum mechanics: a photon 's energy is equal to its frequency multiplied by the Planck constant, and the wavelength of a matter wave equals the Planck constant divided by the associated particle momentum.
Vor 3 Tagen · Gouy phase is a wave phenomenon that appears when waves are confined transversely to their propagation direction, such as in the case of lens focusing and diffraction through slits. It was...
Vor 2 Tagen · Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
Vor einem Tag · The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1] With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
Vor 4 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 ...
