Problem: Since quantum-mechanical theory is universal, it applies to all objects, regardless of size. Therefore, according to the de Broglie relation, a thrown baseball should also exhibit wave properties. Why don’t we observe such properties at the ballpark?

FREE Expert Solution

We’re being asked to explain why wave properties cannot be observed at the ballpark for a thrown baseball according to the de Broglie relation


Recall that the de Broglie wavelength (λ) can be calculated using:


λ=hmv


where: 

h = Planck's constant (6.626 × 10–34 kg • m2/s)

m = mass (in kg)

v = velocity (in m/s)
