What Happens to Energy Levels in a Reduced Potential Well?

AI Thread Summary
When the potential V is reduced significantly below the zero point energy, the ground state remains unchanged due to the constancy of zero point energy. However, the first excited state may gain enough energy to become unbound from the potential well, leading to a change in its wave function. The wave function transitions to an oscillatory form, indicating the particle is no longer confined. This shift occurs because the energy of the system exceeds the potential energy, resulting in a loss of binding. Overall, the reduction in potential alters the state of the first excited wave function while the ground state remains stable.

if V is reduced to much smaller than the zero point energy then what happens to the ground state and first excited state?


for this i know that the function becomes continuous and that the particle is unbound. does this mean that the function will also just have an oscillatory form?

What are you asking exactly? you should know that shifting of potential V with a constant value Vo does not change the wavefunction.
 
yeah but if you change V from it being originally greater than E to being much smaller than the zero point energy surely this would change the ground and first excited wave function? wouldn't the fact that the E of the function is greater than V mean that it is no longer bound by the potential well?

i have these ideas but I am not sure if they are right and unfortunately this is not looked at in any of the books I've read.
 
so after thinking on it believe the ground state would stay the same as is the zero point energy which doesn't change, but then would the 1st excited state have enough energy to become unbound from the potential well
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
