<p>Is this on the exam? I've heard there was a few multiple choice questions, but my class is doing binding energies and such, and I just want to know if it will be on the free response. The multiple choice I can handle, its just this section is kinda trippy for me.</p>
<p>Thanks.</p>
<p>You should know e = mc^2, de broglie’s wavelength, E = hf = pc, wavelength = c/f, and how to apply them.</p>
<p>I believe every physics b exam has had a question on atomic physics as it’s last question. Most of them involve particles colliding and creating photons, although a lot of them either ask you to conduct some experiment, or calculate the resulting energy and such. I know de broglie’s wavelength is a big one that almost every question asks for.</p>
<p>Alright, I’m pretty okay with the stuff you mentioned, thanks.</p>
<p>What’s bothering me right now is this binding energy stuff, E = delta m * c^2. That delta m (mass defect) is a pain in the butt.</p>
<p>Thanks.</p>
