Worked practice questions

For very slow electron (low momentum), de Broglie wavelength is:

  1. Zero
  2. Very small
  3. Doesn't apply
  4. Very LARGE (λ = h/p; small p → large λ)
Show answer and solution

Correct answer: D. Very LARGE (λ = h/p; small p → large λ)

λ = h/p. Slow particle → large λ. Electrons at thermal speeds have λ ~ atomic dimensions, making electron diffraction observable (Davisson-Germer 1927).
