A particle is in a finite potential well, and it can have any one of 5 quantized energy values and no more. What would allow it to have possibly a 6th energy level?

A particle is in a finite potential well, and it
can have any one of 5 quantized energy values and
no more. What would allow it to have possibly a
6th energy level?

1. Increase the energy of the particle
2. Decrease the energy of the particle
3. Make the well wider
4. Make the well narrower
5. Make the well shallower

A particle moving from the left to the right with
energy E encounters a barrier with UgtE. The
particle tunnels through the barrier. Its
wavelength after the barrier

1. Is the same as before the barrier
2. Is smaller after the barrier than before
3. Is larger after the barrier than before
