what is the difference between emitter and absorber

Difference between emitter and radiator
Shiny surfaces are poor absorbers and emitters (but they are good reflectors of infrared radiation). If two objects made from the same material have identical volumes, a thin, flat object will radiate heat energy faster than a fat object. This is one reason why domestic radiators are thin and flat.
Answer:
A poor emitter is also a poor absorber and a good absorber will also be a good emitter.
Explanation:
A block of material used to absorb some of the energy of an incoming particle is called an absorber. Depending on the application, absorbers can be composed of a variety of materials; popular options include lead, tungsten, and liquid hydrogen.
Shiny surfaces perform poorly as emitters and absorbers (but they are good reflectors of infrared radiation). A thin, flat object will emit heat energy more quickly than a fat object if two objects made of the same material have identical volumes.
According to Kirchhoff's radiation law, objects that are good emitters are also good absorbers. A surface that has been blackened is both a great emitter and absorber. The same surface becomes a poor emitter and a poor absorber when it is silvered. Any radiant energy that strikes a blackbody is completely absorbed by it.
