1. ### Why does an alpha particle curve less in a magnetic field than a beta?

Suppose you are analyzing this image. The question to answer is: Explain why the alpha particle's path has a larger radius than either of the beta particle paths. Justify your answer using either momentum or charge-to-mass ratio. When you are answering this, suppose you know that , in...
2. ### B In a nuclear decay, is all of the released energy kinetic energy?

I'm trying to make up an example for my students to illustrate that in nuclear decay, mass-energy and momentum are both conserved. I found this problem: https://physics.stackexchange.com/questions/304277/calculate-velocity-of-radon-220-nuclear-after-decay I am trying to modify it so that they...
3. ### Bohr Model - Absorbing a Photon with Enough Energy to Ionize the Atom

I just want to confirm something. You need about 13.6 eV of energy to ionize a hydrogen atom in the ground state. Can the atom absorb a photon with 15 eV of energy? I think it can. This would free the electron, and the freed electron would move off with a kinetic energy of 15 minus 13.6 eV...
4. ### How does polarization show the wave nature of light?

I'm a high school teacher. In the curriculum, students are required to explain that polarization of light shows that light is a transverse wave. My answer: In order to explain polarization, we have to consider the electric field vibration direction. For example, on a wave that propagates...
5. ### Strong Nuclear Force & Particle Accelerators

I am a teacher and the problem statement is part of our curriculum. I feel like I have a basic understanding of what particle accelerators are, but I only have a vague idea of what the strong nuclear force has to do with this. Here's what I know: In a particle accelerator, you might smash...
6. ### Why do nuclei form in the first place if the protons repel each other?

Now that I think about this some more, nucleons can get close together if they are traveling at a very high speed. So maybe when the Earth first formed, stuff was moving fast (or at high temperature/pressure) and this forced nucleons together into nuclei? I don't really know what I'm talking...
7. ### Polarization of Light Analogy Question

Homework Statement Hi everyone, I'm a high school teacher and every time I teach the concept of polarization, students ask me the same question and I can't answer it. I show students this picture. The red lines show the electric field vibrations. After passing through polarizer 1, the...
