    Concepts Quantum
AI Thread Summary
The discussion revolves around the true or false evaluation of several quantum mechanics statements. Participants express uncertainty about the nature of wave functions, with the consensus leaning towards the idea that all objects, not just small ones, have wave functions. The second statement regarding electrons showing wave-like interference is debated, with some affirming its truth based on experimental evidence. Clarification is sought on the relationship between the wave function and probability density, with agreement that the absolute value squared of the wave function represents probability density. Overall, the conversation highlights the complexities of interpreting quantum concepts and the need for precise understanding.

Homework Statement


TRUE or FALSE for each statement:

*Only very small objects have a wave function.
*Electrons show interference effects like waves.
*The wave function times the volume gives a measure of the probability of finding a particle in a particular region.
*The absolute value of the square of the wave function can be thought of as a probability density.
*No two electrons may occupy the same quantum state in an atom.
*Two photons may occupy the same quantum state.


Homework Equations





The Attempt at a Solution


I'm finding vague answers to these concepts in my book, but I just wanted some clarification because it's hard to completely digest the language used. I've only heard of wave functions in quantum, so I'm assuming the first is true? The second is false, because the idea of an electron in quantum is probability, not a physical particle itself. The third statement is logical to me, but anytime I've normalized a probability integral I've always used the absolute value of the wave function squared. So I'm not sure about that. In that regard, the fourth statement I'm familiar with, but I'm not sure if it's defined as the "density". The fifth statement is true. And I'm almost positive the sixth is true because photons are bosons.

Any corrections of my logic or guidance? I would appreciate it!

The first seems true, but yet, everything has a wave function, and everything "obeys" if you will quantum physics. A human would defract through a doorway, were he to take 1 step every several billion years or so. Beware of this question, it is false, yet only seems true.

The second seems true to me. Electrons will behave like waves in double slit experiments, showing an interference pattern, but when you try to 'detect' them, you cause them to recoil and pickup their particle properties.

Third is false, it's the wave function squared.

fourth is true.

fifth is true

Not sure about the 6th, if you say true, so be it
 
It was right! Thank you very much :)
 
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...
