Lasers with visible light (or at least in that frequency range) can be used to detect hyperfine interactions. In this video you’ll learn how. At the bottom of this page, you find an optional video of a conference presentation about laser spectroscopy.
When the video stops to ask you a question, fill out your answer in this Google form. Don’t alter your answer after you watched the rest of the video. If you have second thoughts about your initial answer, write them in the optional text box of the Google form.
The second task is based on a paper by Forest et al. (J. Phys. G: Nucl. Part. Phys. 41 (2014) 025106). You don’t necessarily have to read the paper (although feel free to do so), we’ll focus on Table 1 that is reproduced underneath. Use the information in this table and the NIST data base to make a neat energy level diagram for Ru with some transitions shown – similarly as shown in the video for Lanthanum. The drawing can be made by hand on paper (scanned to pdf). Upload your drawing via the ‘quiz’ button underneath.

Although this web site calls this a ‘quiz’, it is not really one. It’s just a way for you to upload your pdf file with answers. If your file would be too large to upload, use this free online tool to compress it (we recommend to do that anyway).

This response will be awarded full points automatically, but it can be reviewed and adjusted after submission.
As optional material, you can watch this conference talk by G. Farooq-Smith. You’ll get an explanation of laser spectroscopy through the mouth of someone using the method. I bet you have the knowledge now to understand a lot of it! The relevant content is:
