# Formula Compton Scattering Wavelength before    Scattering angle

## Wavelength before

Unit
Wavelength of the photon before the collision.

## Wavelength after

Unit
Wellenlänge des Photons nach dem Stoß.

## Scattering angle

Unit
Scattering angle between the two momentum vectors of the photon after and before the collision.

## Mass

Unit
Mass of the particle (e.g. an electron) at which the photon is scattered.

## Planck's Constant

Unit
Planck's constant is a physical constant and has the value: $$h = 6.626 \cdot 10^{-34} \, \mathrm{Js}$$.

## Speed of light

Unit
Speed of light is a physical constant and has the value in vacuum: $$c = 299 \, 792 \, 458 \, \frac{\mathrm m}{\mathrm s}$$.
