Electrons passing through crystals are diffracted because they
- are repelled by the atoms in the crystal
- are attracted by the atoms in the crystals
-
possess wave properties
- are particles
The correct answer is: C
Explanation
Electrons passing through crystals are diffracted due to their wave properties. This wave-like behavior allows them to interact with the periodic arrangement of atoms in the crystal, leading to diffraction patterns similar to those seen with light waves. Thus, the correct answer is C. possesses wave properties.
