Here’s just what you need – a review of frequency, wavelength, and energy problems. Make sure you know not only the formulas, but also the symbols and units of wavelength, frequency, energy, speed of light, and Planck’s constant.

Here’s the lecture from today on the photoelectric effect. How’d you like the field trip? What are some other applications of the photoelectric effect?

I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Here’s the beginning lecture from Wednesday, we’ll talk more about it tomorrow. First – an overview of the problems with Planck’s constant. Kind of crazy at the beginning, but I want you to make sure you’re not just writing down formulas and plugging in numbers without understanding why. Understand why and you’ll get them right every time! :)

Have you ever seen it in person? I’m betting you have! Here’s the lecture from Tuesday. Good job on the problems today. Make sure you are careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused.
