Calculate K Excitation Voltage & Wavelength of Copper

[asdf1]

for these problem:
1.calculate the K excitation voltage of copper.
2. calculate the wavelength of the Cu K(alpha 1) line.

my problem:
with that limited amount of information, how are you supposed to calculate it?

You're going to need some tabulated data. http://xdb.lbl.gov/ is the place to get that. For 1. you'll need the binding energy of the K electrons.

For 2.. do you know what transition the K_alpha 1 line is equivalent to? You'll need the relevant energy difference.

wow~ thanks! but i think my textbook wants me to calculate it without the data, but is that possible?

Calculating the binding energies is not a trivial matter. I really really really doubt that that would be what your textbook wants you to do.
