Calculate K Excitation Voltage & Wavelength of Copper

Click For Summary

Homework Help Overview

The discussion revolves around calculating the K excitation voltage of copper and the wavelength of the Cu K(alpha 1) line. Participants are exploring the necessary information and methods to approach these calculations.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need for tabulated data, specifically the binding energy of K electrons, and question whether calculations can be performed without this data. There is also inquiry into the specific transition associated with the K(alpha 1) line.

Discussion Status

The discussion is ongoing, with some participants suggesting that certain data is essential for the calculations, while others express skepticism about the feasibility of performing the calculations without it. There is no explicit consensus on the approach to take.

Contextual Notes

There is mention of potential constraints imposed by the textbook, which may require calculations without access to necessary data, leading to uncertainty about the expectations for the problem.

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?
 
Physics news on Phys.org
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.
