At a glance:λ_c = h/(mc); reduced λ̄ = ħ/(mc). Complements compton-scattering and mass-energy-equivalence.
Formula
λ_c = h/(m c).
$$\lambda_c = \frac{h}{mc}, \quad \bar{\lambda}_c = \frac{\hbar}{mc} = \frac{\lambda_c}{2\pi}, \quad E = mc^2$$How to Use
- Enter a mass.
- The tool returns the Compton wavelengths and rest energy.
