Physics 3-23-12 Waves

PHYSICS: Happy Friday! Here’s the lecture on the properties of waves. Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = Ξ»f).

And hey, did you figure out that problem from the end of class yet? It’s not that difficult, really. πŸ™‚ Bring me the answer on Monday, and let’s take waves a step further then. Have a great weekend!

Chemistry 1-23-12 Photoelectric Effect

CHEMISTRY: Fun field trip today! What? There really aren’t tiny people living in boxes above the doors at Wal-mart? Good job coming up with examples of the photoelectric effect. I hadn’t ever thought about those automatic flush toilets! πŸ™‚

What did you think about the problems? Again, make sure you not only memorize formulas, but also be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused. Here’s the lecture from Monday – well, not exactly. Someone, and that would be me, forgot to turn on the mic, so here’s a blast from the past that will work.

Chemistry 10-4-11 Chapter 1 Test

CHEMISTRY – Finally! The end to chapter 1. Here’s the rest of energy (kinetic and potential) and then the test review Good luck studying! Make sure you aren’t just reading your book and notes. First, memorize the facts, then go back and make sure you can apply the concepts. Study examples, make your own examples, practice making questions. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, click here for the Chap 1 Study Suggestions. You can do this – I believe in you! I’m praying for you!!
