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 1-20-12 Wave Properties of Light

CHEMISTRY: So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Friday on just that. Make sure you know the types of electromagnetic radiation and the uses of most of them (all except for long waves). How’d you like the light problems – so far? We’ll explore waves further Monday – make sure you bring a calculator to class!
