A parallel beam of fast moving electrons is incident normally on a narrow slit. A fluorescent screen is placed at a large distance from the slit. If the speed of the electrons is increased, then which of the following statements is correct?

Options

  1. ADiffraction pattern is not observed on the screen in the case of electrons
  2. BThe angular width of the central maximum of the diffraction pattern will increase
  3. CThe angular width of the central maximum will decrease
  4. DThe angular width of the central maximum will be unaffected

Correct answer

B. The angular width of the central maximum of the diffraction pattern will increase
