Potentially a really stupid question, but when you make 2 mirrors face each other, why does it get continuously darker the further you look down?

Maybe my brain isn't functioning properly today, but I just can't seem to understand it.

Oh, it's just because mirrors aren't perfectly reflective, so some percent of light gets absorbed during each reflection.


I actually never noticed this effect before. Next time, I'll keep an eye out.
