Answer: The two properties that indicate wave-like nature of an electron is its motion and electrons diffraction and interference in a beam.
Step-by-step explanation:
The term diffraction refers to when a light from a point source hits an obstacle then the waves are spherical and forms a fringed image pattern.
Whereas interference refers to when two or more wave trains move on intersecting or coincident paths, then their net effect is called interference.
Therefore, it can be concluded that the two properties that indicate wave-like nature of an electron is its motion and electrons diffraction and interference in a beam.
