AP Physics B Atomic/Nuclear Physics

<p>What types of problems are we suppose to know specifically about Atomic/Nuclear Physics?</p>

<p>I have the outline but I can't really tell what exactly want they want you to know for the exam. =/</p>

<p>Just off the top of my head:</p>

<p>All those nuclear reactions (decay, electron capture... etc): just adding up stuff
Photoelectric Effect: how much current flows for a certain amount of light for a certain material. calc work function or Plank's constant
KEmax vs Frequency graph and work functions, slope = Plank's constant: enough energy? how much KE? Will ionization happen?</p>

<p>And anything having to do with the wavelength and energy relationships. Wavelength of a particle... etc.</p>

<p>K= eV (that's helpful)</p>

<p>Actually I meant just the nuclear section, sorry. I'm just not sure what kinds of equation I need to learn how to solve for fusion/fission on the exam. I also don't really know what they mean by "mass-energy equivalence." What decay processes do you need to know? There are like alpha particle decay, beta, etc, etc..</p>

<p>bump.... anyone?</p>

<p>like most said above Planks Constant
hf=energy of a photon of light
E=mc^2 what is the actual mass of an atom, Energy taken up by binding.</p>

<p>photo electric effect and using the energy of a photon and seeing if it will be enough energy to break the binding energy of a atom.
Alpha particle is a helium atom
- and + beta decay
gama decay does nothing</p>

<p>yea, know your decays (alpha, beta, gamma) and the other processes, like electron capture... I have my packet of the list if you want to know, but I'm sure you have one too.</p>

<p>I think you might also have to know the neutrinos that come off.</p>

<p>oh, and energy mass equivalence is just E=mc^2</p>

<p>ugh the decays look so confusing!</p>
