Choose the wrong statement.

Options

  1. AAlpha particles can be scattered by Gold nucleus.
  2. BX-ray can be diffracted by crystals.
  3. CUV-radiation can cause photoelectric effect.
  4. DElectrons cannot be diffracted by crystals.

Correct answer

D. Electrons cannot be diffracted by crystals.

Step-by-step solution

Electron wave is used in place of X-rays to study crystals of larger dimensions in electron crystallography. So, they can be diffracted.
