de Broglie wavelength of a 1 kg ball moving at 1 m/s:
A~10⁻¹⁰ m
B~10⁻³⁴ m (= 6.6 × 10⁻³⁴ / 1)
CInfinite
D1 m
Answer & Solution
Correct answer: B. ~10⁻³⁴ m (= 6.6 × 10⁻³⁴ / 1)
λ = h/p = 6.6 × 10⁻³⁴ / 1 = 6.6 × 10⁻³⁴ m. Far smaller than atom or even nucleus. Hence quantum effects undetectable for macroscopic objects.
