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

AZero
BVery small
CDoesn't apply
DVery LARGE (λ = h/p; small p → large λ)
Answer & 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).
