🤓 Based on our data, we think this question is relevant for Professor Budziak's class at COD.

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 • m^{2}/s)

**m** = mass (in kg)

**v** = velocity (in m/s)

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?
