re: #189 b_sharp

They are absorbed by some material and their energy heats it up. Some, depending on wavelength, bounces off, so there isn’t just one reaction to an object.

Some particles (neutrinos) are small enough they pass through the empty space of molecules and atoms. We’re mostly empty space.

Yeah, yeah, matter absorbs all the lightwaves in the visible spectrum that it is. Grass isn’t really green—I can understand that. But does it reflect, or refract the colors it isn’t?

How does one determine if it is polarized?
