Ways to bend radiation question?

[philrainey]

I'm fascinated by radiation as I have been learning a tidy bit about it. I have learned that radiation can be bent by refraction and have heard some idea that it can be bent by gravity ie a black hole. What other things bend electromagnetic radiation? Does electromagnetic radiation get bent passing through a magnetic field or a electrical field. Since this is what these waves are made of I thought perhaps they may be affected by these fields. Are there other effects that bend electromagnetic radiation?

What kind of radiation are you referring too? The word radiation can be define as: "the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay" which really is just a method of energy transfer. EM radiation can be manipulated only by gravity and matter, as far as I know (not far). While particle radiation, such as beta decay, can be manipulated by mass, gravity, and EM fields.

I don't know about the "jelly vacuum" theory, I've never heard of it.

I'm thinking about heat radiation across a vacuum from a hot body (say 3000 degrees C to a cold body (say 1500 degrees C). I suppose at that temperture some of it will be visable light?
