HON CHEMISTRY: Isn’t this a super cool picture of light? So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves?
How’d you like the light problems so far? I forgot to hit “resume recording” after I paused, I’m posting a lecture from last year. We’ll resume with the photoelectric effect tomorrow!
Hon Chemistry 1-10-17 The Electromagnetic Spectrum & Wave Properties of Light UPDATED from Tammy Skinner on Vimeo.
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 = λf).
And hey, did you figure out that problem from the end of class yet? It’s not that difficult, really. 🙂 Bring me the answer on Monday, and let’s take waves a step further then. Have a great weekend!
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!
