Finding the Scattering Angle of a 0.88Mev Photon & Electron

[bluesnake]

A 0.88Mev photon is scattered by a free electron initially at rest such that the scattering angle of the scattered electron is equal to the scattered photon.How to find the angle??

Hi, i tried already.My teacher only give us this formula.
lamdai =lamda o+ lamda(c)Contant* (1-cosdegree)
the problem is i don't have the other information n lamda.how to sub ?

This is a beginning. To get background information got to
http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/comptint.html
Once there, read about Compton scattering and be sure to click the link "Develop formula" This should get you started about what is going. If you still have questions, do come back.
