Definition:Compton Wavelength

Definition
Let $P$ be a particle.

The Compton wavelength of $P$ is defined as the wavelength of the photon which has the same rest energy as $P$.

It is defined as:
 * $\lambda = \dfrac h {m c}$

where:
 * $\lambda$ denotes the Compton wavelength of $P$
 * $m$ denotes the mass of $P$
 * $h$ denotes Planck's constant
 * $c$ denotes the speed of light.
