How much does light penetrate through a solid material in microns.
There more than a million atoms in the width of a human hair, so with...light shining on the hair how many single atoms in a line, would the light
traverse through, or maybe the better word to use is scatter through.
The light is getting absorbed by the electron, and emission-ed, but some light is getting through the solid material, but by how much.
Thank you for your help, anything helps even a few words.

Define "light."
What solid material? Lead? Glass?

About half of visible light is absorbed passing through 5 nm layer of aluminum.

If your material is an optical fibre, and the light is near 1550nm (Infra red- but the idea is still pretty much the same as visible light) then about
half the light will penetrate roughly 15 kilometres.
That's 15,000,000,000 microns.
