Hi, I need some guidance on a particular question for my coursework.(adsbygoogle = window.adsbygoogle || []).push({});

The questions states:Calculate the wavelength of L(alpha) and L(beta) x-ray photons produced from a copper target (Z=29)

I have tried finding the wavelength using E=hc/lambda and re-arranged for lambda (lambda=hc/E)

Is this the correct approach to solving the problem? Alpha and beta rays travel at the same speed ~ 3*10^8m/s, seems like I'm missing something.

I don't want answers as this doesn't help me in any way but just need some guidance as to how it can be worked out.

Your help is much appreciated..
