Hon Chemistry 1-6-12 Wave Properties of Light

HON 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!
