Solved: Wavelength of Scattered Light After Photon-Electron Collision

[Allan1993]

Can someone please help me??

A photon collides with an electron and is scattered backwards so that it travels back along its original path. Describe and explain the expected wavelength of the scattered light.

Relevant equations: I'm not sure it's required here, this is more theory rather than calculations



I have no idea what this is on about so i haven't attempted the question. Sorry.

If it's a high energy photon then I recommend looking into Compton scattering.
