Is the appearance of a light wave changed as it is aborted?

Light waves are never 'aborted'.

They can be 'absorbed', and I think that's what you mean.

It's what happens when light hits something or goes into it,

and never comes out.

"Absorb" just means "soak up". When a light wave hits something and

gets soaked up in it, it's gone, and never comes out the other side.

The light wave certainly gets changed ... it no longer exists.

The object that absorbs it also gets changed. It soaks up the energy

in the light wave, and it has a little more internal energy (heat) than it

had before the light hit it.
