You get a net flux away from an object that is warmer than its environment, and toward an object cooler than it's environment.
Typically emission is in the long-IR wavelengths.
The wavelengths are affected by the surface properties of the object. Black objects emit at virtually all wavelengths, according to the Stefan-Boltzmann expression. Other colored objects emit less.
Reflectivity is the inverse of emission, so shiny, refelective surfaces do not emit well.

One is that it travels by a vacuum. you would be able to make up any rubbish for those form of questions - whether i think that's no longer what your instructor needs to hearken to...... different concepts - it is a sort of electromagnetic radiation interior the infra-pink spectrum. you would be able to desire to google the wavelength. Mmmm i'm runnig out of concepts, desire somebody else solutions
