Does the frequency of incident light change in Beer-Lambert Law?

The [Beer-Lambert law](https://en.wikipedia.org/wiki/Beer%E2%80%93Lambert_law) is meant to describe the interaction between a solute and incident light.


But, does the frequency of the light here change due to the interaction with molecules?


I think there is a change in the intensity of light, not in the frequency. But this seems counter-intuitive.


Is there no change, or is it so small that it's just neglected?
