Understanding the Answer
Let's break down why this is correct
Answer
The Davisson‑Germer experiment is the classic example that shows electrons behave like waves. In that experiment, a beam of electrons was fired at a nickel crystal and the scattered electrons produced a diffraction pattern, just like light waves diffract through a crystal lattice. The pattern could only be explained if the electrons had a wavelength, which was calculated using the de Broglie relation. This experiment proved that particles such as electrons can exhibit wave‑like properties, just as light does. Thus, the Davisson‑Germer experiment best illustrates the wave‑like behavior of electrons.
Detailed Explanation
When electrons go through two narrow openings, they spread out and overlap, creating bright and dark spots on a screen. Other options are incorrect because Many think the heat of a filament makes electrons move like waves, but it really only frees them as particles; Accelerating electrons in a vacuum tube is similar to pushing a ball with a force.
