Hi,
I'm trying to derive a simple formula for 180° scattering.
I've got to this stage and I really can't figure out how to simplify it further.
[tex]\[ \frac{1}{\lambda}-\frac{1}{\lambda'} = \frac{2m_ec}{h} \][/tex]
What I actually need is:
[tex]\[ \lambda' - \lambda = \frac{2h}{m_ec} \][/tex]
I'm pretty sure the first formula is right but I can't seem to simplify it into the second!
Thanks in advance.
