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.
