Question

How does radiation play an important role in the functioning of room heater??

Answer 1

Radiation occurs when heat radiates across the space between you and the objects in your home. If objects are warmer than you are there, heat will travel toward you. Removing heat through ventilation reduces the temperature of the ceiling, walls, and furnishings. The cooler your surroundings, the more you will radiate heat to the objects, rather than the other way around.
so we can say that radiation plays an important role in functioning of room heater.
