Why are de Broglie waves associated with a moving football is not apparent to us?

Explanation

To understand why de Broglie waves associated with a moving football are not apparent to us, we can follow these steps:

### Step 1: Understand de Broglie Wavelength
The de Broglie wavelength (\( \lambda \)) is given by the formula:
\[ \lambda = \frac{h}{p} \]
where \( h \) is Planck's constant and \( p \) is the momentum of the object.
