## Homework Statement

If the maximum energy transferred to an electron during Compton Scattering is 50KeV, what is the wavelength of the incident photon?

## Homework Equations

[tex]\lambda[/tex]' - [tex]\lambda[/tex][tex]_{o}[/tex] = h/(Me*c)(1-cos[tex]\theta[/tex])

## The Attempt at a Solution

We know that the maximum energy transfer for compton scattering occurs when:

[tex]\theta[/tex] = 180

[tex]\phi[/tex] = 0

So when [tex]\theta[/tex]=180

[tex]\lambda[/tex]' - [tex]\lambda[/tex][tex]_{o}[/tex] = 0.00486nm

Everything I've tried looking up involves the scattered photon as well (like the momentum, energy, wavelength equations)

Any tips on where to look/where I can go next?
