1. The problem statement, all variables and given/known data[/b
Robinett question
One of my homework questions in the Compton scattering section asks:

"Evaluate the fractional change in wavelength delta lambda/lamdba, for incident blue light and X-rays? It also gives the wavelength of blue light and X-rays.

I do not know what this questions wants because the Compton scattering equation takes 3 parameters(lambda, lambda', and theta) and they only give 1 here (lambde_blue light or lambda_X-rays). Anyone want to rephrase this for me?

2. Relevant equations

3. The attempt at a solution

I guess they mean the ratio $\Delta \lambda/ \lambda$, where \Delta \lambda =\lambda' -\lambda. But i don't know what you should do with the angle...
