How do electrons colliding at crystal result in diffraction?

Question: How does the electron beam colliding at the crystal result in diffraction if it is not a wave?

Answer: A beam of electrons seems to act the same way: like a wave, spreading and bending as it hits the tiny spaces between atoms in a crystal. Going to a higher frequency, we can use X-rays to identify crystal structures because different crystals can have different-sized spaces in different places; X-ray diffraction can show how large these spaces are and where they are compared to each other.
