Which is true about the absorption of a photon by an electron in a one-dimensional, infinite potential well?
The photon energy must be equal to the energy difference between the electron’s current energy level and the next lower level.
The photon energy must be equal to the energy difference between the electron’s current energy level and the next higher level.
The photon energy must be equal to the energy difference between the electron’s current energy level and any lower level.
The photon energy must be equal to the energy difference between the electron’s current energy level and any higher level.
