Reply to comment by Chemomechanics in Does refracting light impart momentum onto the object that is refracting it, for the duration of the refraction? by TheFeshy

The light must give some of its energy to the medium so if the frequency doesn't change then where does this energy come from.

Well, what's different about monochromatic light that's passed through a filter?

I don't know. I am a normal dude in IT that spends too much time on the internet. I have a middling understanding of this stuff and am curious. If a refractory medium like a lens behaves differently than a filter that would be interesting. 😁

I was just looking for “It’s dimmer.” That’s what provides the energy that’s absorbed in the medium, not any change in frequency.
