Overview
The Compton wavelength is a quantum mechanical property of a particle, defined as the wavelength of a photon whose energy is the same as the rest mass-energy of that particle.
💡
Pro Tips
The Compton wavelength is inversely proportional to the mass of the particle.
The 'Reduced' Compton wavelength is λ divided by 2π.
For an electron, λ ≈ 2.426 pm.

Fun Facts
"The Compton wavelength sets the scale below which quantum field theory becomes important."
"It can be thought of as a limitation on measuring the position of a particle."
"If you try to locate a particle to within its Compton wavelength, you have enough energy to create another particle of the same kind."
