The electron excites the molecule. When the molecule relaxes to its ground state, it releases photons.
Is it the transfer of energy from the electron to the molecule that disrupts the interference pattern? Or is it the interaction between the electron and photons (i.e. electron losing momentum)?
Question
Suppose molecules are placed next to the slits that fluoresce when electron passes, emitting a photon that can be imaged. Explain why this is no better than direct illumination, and explain how the two-slit interference pattern is destroyed.
My Answer
In direct illumination, a...
Thanks for the reply. We're not allowed to double count courses for a double major. So a double major is not possible, even though I will be meeting the requirements for both.
I'm sure admissions committees pay more attention to coursework, so that's not my main concern. My main concern is...
I'm interested in both physics and engineering. After undergrad, I would like to pursue a masters in engineering, then a PhD in physics.
Right now, I'm taking both physics and engineering courses. I will meet the requirements for both the physics or engineering physics major. Since my...
I'm applying for spring term courses and will soon be declaring, so I'd like to renew this thread again. I'm not sure if it'd be useful to post my entire four year curriculum, so I'll summarize. If I continue with mechanical engineering, I still plan to take the necessary physics courses to...
I was a mechanical engineering major that recently switched into physics. Given my late start, I'll be taking most of the physics curriculum in 2.5 years. Is this enough time to adequately prepare for PhD work? Since I'll be taking quantum my senior year, I probably won't take the GRE until...
I am sophomore that just recently switched into physics from engineering. As a result, my physics background is weaker than most sophomores. I'm applying for a summer research grant at my university, and I'm trying to find a professor to work with.
I've browsed through all the faculty research...
Don't get me wrong, I think mechanical engineering is very interesting. By 'more useful and valuable', I didn't mean 'more hireable'. I meant that it is more relevant toward my goals and will ultimately make me the better engineer. With mechanical engineering, I would have a better toolbox to...
Choosing a Major
I'm a sophomore undergrad at Stanford that is interested in biotechnology. I was majoring in bioengineering, but recently switched to mechanical engineering. Main reasons were because the bioengineering program here is too new and I'd rather have a broader engineering...
