Which phenomenon BEST supports the theory that matter has a wave nature?*1 pointphoton diffractionelectron diffractionphoton momentumelectron momentum

The phenomenon that best supports the theory that matter has a wave nature is electron diffraction.

Here's why:

1. The wave nature of matter is a fundamental concept in quantum mechanics, which suggests that all particles of matter exhibit both particle and wave characteristics. This is known as wave-particle duality.

2. Electron diffraction is a direct observation of this wave-particle duality. In this phenomenon, electrons behave like waves and create an interference pattern when they pass through a crystal lattice or a thin film. This is similar to how light waves create an interference pattern when they pass through a diffraction grating.

3. Photon diffraction and momentum (both photon and electron) are related phenomena, but they do not directly support the wave nature of matter. Photon diffraction is a wave phenomenon, but photons are particles of light, not matter. Momentum, on the other hand, is a property of both particles and waves, but it does not directly demonstrate the wave nature of matter.

So, electron diffraction is the best answer because it directly demonstrates the wave nature of matter.
