Answer: Spacing between atomic layers
Explanation
- Electrons exhibit diffraction effects because their de Broglie wavelength is similar to the spacing between atomic layers in a crystal.
- The de Broglie wavelength of an electron is given by λ = h/p, where h is Planck's constant and p is the electron's momentum.
- For electrons in a crystal, this wavelength is typically in the range of 0.1-1 nanometers, which is similar to the spacing between atomic layers in the crystal.
- As a result, electrons interact with the crystal lattice and exhibit diffraction effects, such as bending around corners or passing through the crystal in specific directions.
