Question

1. As we increase the quantum number of an electron in a one-dimensional, infinite potential well, what happens to the number of maximum points in the probability density function?

It increases.

It decreases.

It remains the same

2. If an electron is to escape from a one-dimensional, finite well by absorbing a photon, which is true?

The photon’s energy must equal the difference between the electron’s initial energy level and the bottom of the nonquantized region.

The photon’s energy must equal the difference between the electron’s initial energy level and any energy value in the nonquantized region.

The photon’s energy must equal the difference between the zero energy level and the bottom of the nonquantized region.

3. If two quantum states are degenerate, which is true?

They have identical wave functions.

They have identical momenta.

4. Which is true about the energy levels of hydrogen?

Their spacing increases as we move up through the levels.

They are evenly spaced.

Their spacing decreases as we move up through the levels.

5. Which is true?
