AI Thread Summary
The discussion revolves around calculating the probability of finding a particle in a one-dimensional box between 0 and a/4 as quantum numbers become large. The Correspondence Principle suggests that quantum systems behave classically in this limit, implying equal probability distribution across the box. It is established that if the total probability of finding the particle in the box is 1, then the probability of finding it in the segment from 0 to a/4 is indeed 1/4. This conclusion is confirmed by participants in the discussion. The application of the Correspondence Principle effectively supports the equal probability assertion in quantum systems.

Homework Statement


For a particle in a one-dimensional box of length a, I am attempting to find the probability that the particle will be located between 0 and a/4, in the limit of large quantum numbers.

Homework Equations


The Correspondence Principle states that quantum mechanical systems may be described by classical physics in the limit of large quantum numbers.

The Attempt at a Solution


I understand that classically the particle has an equal probability of being anywhere in the box. So, by the Correspondence Principle for large quantum numbers the particle also has an equal probability of being found anywhere in the box. Assuming a normalized wavefunction, the probability of the particle being between 0 and a is 1. Then, am I correct in thinking that the probability of the particle being between 0 and a/4 is 1/4?

Thanks.

Yup! :biggrin:

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 '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...
