Position of particle in infinite potential well

AI Thread Summary
The discussion focuses on calculating the probability of finding a particle in an infinite potential well for energy levels n=1 and n=8 within the region a/4<x<3a/4. The user successfully integrated the probability amplitude to find these probabilities but is confused about comparing them to the classical result. Classically, the probability of finding the particle in that region is 0.5, as it assumes equal likelihood across the well. The user seeks clarification on how classical modeling leads to this probability. Understanding the classical model's assumptions is essential for making the comparison clear.

Homework Statement


For the case n=1, calculate the probability that the particle is found in within the region a/4<x<3a/4 (n is the energy level, a is the width of the infinite potential well). Compare this result with the case n=8 and with the classical result.


Homework Equations


Schrödinger equation.


The Attempt at a Solution


I've calculated the probabilities for n=1 and n-8 by integrating the square of the probability amplitude over the required region. I'm totally confused by comparing it to the classical result, though. I'm not sure what this is asking? Classically, would there be an equal probability of finding the particle anywhere, so this would just be 0.5?

That's right. Classically, the probability is 1/2.
 
Why? Please can you point me to somewhere that explains how this situation is modeled classically?
 

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...
