### Frequency doesn't match energy difference

When frequencies of light don’t match the energy differences of an atom, what happens to the light? Does this light simply pass through?

I am not sure I understand the question but in order for electrons to either jump up to another level or to fall back down, it needs to absorb or emit a specific amount of energy. If it doesn't have that specific amount of energy or doesn't lose that amount, it can not go to that energy level. I think the light passes through if it doesn't supply enough energy for the electron to jump up to another level.

Yes, the light simply passes through the object. Professor Lavelle mentioned this briefly in class.
