Matter waves of molecules as large as carbon \(C_{60}\) have been measured. All physical objects, small or large, have an associated matter wave as long as they remain in motion. The universal character of de Broglie matter waves is firmly established.

- 6.2: Interpreting Matter Waves
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.
We’ll start with the matter wave’s wavelength, known as the de Broglie wavelength: \[\dfrac{2\pi}{\lambda}=\dfrac{p}{\hbar}\;\;\;\Rightarrow\;\;\;\lambda=\dfrac{h}{p}\] This is the wavelength we need to use in (for example) a double slit calculation to predict interference patterns. Notice that unlike the photon, this wavelength depends ...
Now that we know that everything has both particle and wave properties, we explore how to mathematically describe the wave nature of matter.
28. Feb. 2024 · Examples of Matter Waves in Action. Matter waves play a crucial role in both scientific research and technological applications. They help demonstrate key concepts in quantum mechanics. Here are some key examples: Electron Diffraction: When electrons pass through a thin metal or crystal, they behave like waves.
Matter waves of molecules as large as carbon C 60 C 60 have been measured. All physical objects, small or large, have an associated matter wave as long as they remain in motion. The universal character of de Broglie matter waves is firmly established.
17. Okt. 2018 · 17 October 2018. Exploring the Universe with matter waves. An exotic ultracold gas known as a Bose–Einstein condensate has been produced and studied in space. Such gases could be used to build...
