Vor 6 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.
Vor 5 Tagen · In astronomy, dark matter is a hypothetical form of matter that appears not to interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen.
20. Mai 2024 · energy level. wave mechanics. Recent News. May 18, 2024, 5:47 AM ET (Earth.com) "Impossible" quantum effects seen when squishing atoms together. quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale.
9. Mai 2024 · Essentially a wave equation, the Schrödinger equation describes the form of the probability waves (or wave functions [ see de Broglie wave ]) that govern the motion of small particles, and it specifies how these waves are altered by external influences.

21. Mai 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 3 Tagen · 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.
