Default Light bumps into matter

If matter only absorbs light at definite
frequencies what happens if light that can't
be absorbed hits matter?

If light makes it past the electron(lets say
it's on the other side of the atom) and hits
the nucleus what happens to it if it can't
be absorbed?

Light bumps into matter?

The same applies to free(unbound) electrons.

The main features of radiation by relativistic
electrons are well approximated in the Weizsacker-
Williams method of virtual quanta. This method is
best known for its application to radiation during
elementary particle collisions, but is equally
useful in describing "classical" radiation emitted
during the interaction of a single relativistic
electron with an extended system, such as synchrotron
radiation, undulator radiation, transition radiation
and Cerenkov radiation.

It continues on. Why?

So light is a billiard ball to you?

Nope. Acts like one sometimes, though.

Its bouncy?

Sometimes. It's called Compton scattering.

Scattering isn't bouncing my friend.
Its something else.

Hang on, I thought _you_ were the one that first mentioned the 'bounce' word

As a question my friend.

I don't think they actually touch because they would merge.
But I am talking about when matter CAN'T ABSORB the light.

I think scattering is all in the field.
