Reflection probability in Quantum Mechanics

AI Thread Summary
The discussion centers on the reflection probability formula in quantum mechanics, specifically questioning the derivation of the formula and its relationship to transmission probability, expressed as R + T = 1. Participants express uncertainty about the starting point for proving these concepts and the logical steps involved. There is a suggestion to refer back to the text for guidance on the derivation process. Overall, the conversation highlights a need for clarity on foundational principles in quantum mechanics. Understanding these probabilities is crucial for further exploration in the field.

I have doubt where they got the reflection probability formula from. Someone may know how to find it. I think that ##R + T = 1##. But I'm not sure where the transmission probability formula comes from either.

Kind wishes

Sir, blessed.

I have a doubt where to start in the proof. Not sure what logic to use.
 
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 hanged mass'

Thread 'A cylinder connected to a hanged 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...
