Beam splitter with single photons

AI Thread Summary
When a single photon hits a 50-50 beam splitter, it does not split itself but rather exhibits wave-like behavior, leading to the possibility of being detected in either output path. The interaction can be understood through the principles of quantum mechanics, where the photon behaves as a wave, creating interference patterns. At point x, the probability of detecting the photon depends on the superposition of the wave functions from both paths. The concept of standing waves may apply, but it is essential to consider the quantum nature of the photon rather than purely classical wave properties. Understanding these principles is crucial for analyzing photon behavior in quantum optics experiments.

Homework Statement


Fysikbild.png


So we have a source (OP) that emits single photons of a constant wavelength and angular frequency. The photons hit a 50-50 beam splitter, and are then reflected in the mirrors. Where is says (L) ou (SP) (yay for studying in French!) there is a beam splitter.

What I want to know basically is what happens. What happens when the photon hits the beam splitter? What happens at point x, and what is the probability of detecting a photon there?

The Attempt at a Solution


I think it will become a standing wave, but how does that work with only one photon? Does the photon split itself when traversing the beam splitter? What happens in that case when the two waves meet at the point x, and what is the probability of detecting a photon there?

I would be more than happy if anyone could answer this, as I haven't been able to found a similar problem anywhere and my professor refuses to answer e-mails.

Thank you so so much!

And I am sorry that this is a repost, but I would very much like to have an answer!

Here is my thoughts that might be wrong but...
Perhaps in this example, you should consider using the wave properties of light rather than the quantum properties. I can't imagine a photon splitting but I can imagine the wave splitting and I would agree that there sould be a standing wave pattern at x. Just my thoughts and they may be wrong.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
