- Read the two pages on electromagnetic waves I distributed (You don’t need to deal with the chromaticity diagram though)
- Copy the two diagrams from your textbook as directed in class. The answer to Carissa’s question: No, you do not need to know exact frequencies or wave lengths. You do need to know relative frequencies or wave lengths, e.g. red has a greater/lesser wave length than violet; yellow has a greater/lesser frequency than green.
- Complete the worksheet entitled ‘Isotope Notation’; I’ll get the answer key onto the website; check your answers
- Memorize milli, micro, nano, pico and their correlating exponents (milli = 10^-3)
- Complete the ‘Frequency & Wavelength Practice’ worksheets (you may omit the circled problems); SHOW ALL YOUR WORK; I’ll get the answer key onto the website; check your answers. Textbook examples and OYO will help you with these problems.
Please work to finish these assignments by the end of the day on Thursday. Send me an email once you’ve completed them telling me you’re done OR which specific problems you need help with. It is imperative that you have this material completed and understood prior to the next class and I need to have a clear understanding of where everyone is.
Here are the links to the two videos we did not have time to view in class. Watch them when you get to that portion of the textbook.

I will be providing an opportunity to earn additional points for your lowest test grade. My goal is to have that information out to you before the week is out.
