# Homework Help: How to derive characteristic wavelength of x-ray from energy equation?

1. Dec 11, 2011

Hello. first, sorry for my poor English.

Derive characteristic wavelength from radiation power

This is radiated power from bending magnet (synchrotron storage ring accelerating electron to get x-ray)

and these are wave distribution from storage ring

and what I have to derive is as follows. characteristic wavelength of radiation

I have to derive this equation. professor said I can derive this equation from the first power equation. I have been trying for 3 days. but couldn't find solution.
help...

Best regards.
