Diffraction occurs due to the wave nature of matter and radiation encountering obstacles.
Diffraction of matter and radiation is a well-established consequence of wave-particle duality and quantum mechanics, confirmed across various scales from subatomic particles to massive molecules.
The claim addresses the fundamental physical principle of diffraction resulting from the wave nature of matter and radiation. Multiple retrieved high-quality studies (e.g., matter-wave interferometry with nanoparticles, positronium diffraction, and fullerene diffraction) directly support the proposition that matter exhibits wave properties and undergoes diffraction when encountering obstacles.
