Every moving particle has a wavelength — tiny for big objects, significant for electrons.
The math behind it
λ = Planck's constant ÷ (mass × velocity).
Worked Example
Electron at 10⁶ m/s → ~0.73 nm.
Frequently Asked Questions
Why don't we see it?
For everyday masses the wavelength is unimaginably small.
