Wondering why two different concentrations of the same sample,
would allow more light to pass?

er I don't really understand your question but I ll still have a go.

sample absorbs light, because atoms tend to vibrate more when light of a particular wavelenth is passed through their bonds.

if a sample has more lights passed through than the other, it means that it absorbed less light, meaning that there was less substance present, which means that its less concentrated..

Okay, I get that.
On a bit of side note, does this relate in any way to density?

[monokekie]

Density is the mass(usually for H2O in VCE) per unit of volume, which doesn't really relate to the concentration of substances present in the two samples.

I just think of it as if you have a suspension. If you pass light through it, not all the light is emitted through the other side. The more substance in the suspension, the higher the 'absorption'.
