Well, the last scenario "Air warmed by a floor radiator rises to the top of a room, forcing cooler air downward" actually demonstrates convection, not radiation. But don't worry, I won't hold it against you. Just remember, if you're looking for radiation, you might want to check out a superhero movie or a nuclear power plant, not this particular scenario. Keep your superhero suits ready, just in case!
The scenario that shows radiation is:
Air warmed by a floor radiator rises to the top of a room, forcing cooler air downward.
The scenario that shows radiation is:
Air warmed by a floor radiator rises to the top of a room, forcing cooler air downward.
Explanation:
Radiation refers to the transfer of heat through electromagnetic waves, without the need for direct contact between objects. In this scenario, the heat from the floor radiator is transferred to the air in the room through radiation. As the air near the radiator becomes warmer, it rises and displaces the cooler air in the room, creating a convection current. Therefore, this scenario demonstrates the principle of radiation.
