# 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:

$\overline{){\mathbf{\lambda }}{\mathbf{=}}\frac{\mathbf{h}}{\mathbf{mv}}}$

where:

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

m = mass (in kg)

v = velocity (in m/s)
