de Broglie wavelength λ associated with a particle of momentum p:
Ahc/p
Bh × p
Ch / p (wave-particle duality)
Dp / h
Answer & Solution
Correct answer: C. h / p (wave-particle duality)
λ = h/p. Every moving particle has wave-like properties with wavelength inversely proportional to momentum. For ordinary objects λ is unmeasurably small; for electrons λ is on atomic scale.
