Practice: Electron Diffraction and Microscopy

Which of the following correctly states the advantage of using electrons to produce images of very small objects compared to using electromagnetic waves?

  • AElectrons can penetrate deeper into objects than electromagnetic waves.
  • BA beam of electrons will in no way affect an object that it produces an image of, so it produces a more valid image than the ones that can be produced by electromagnetic waves.
  • CElectrons are reflected from objects more strongly than electromagnetic waves.
  • DElectrons can easily be accelerated to velocities at which they have wavelengths much shorter than those of electromagnetic waves with wavelengths that are useful in forming images.
