Performance Objectives
The student should be able to:
- Describe the method of heat transfer (radiation) and state two of its applications
Content
Radiation
Radiation is another form of heat transfer. It does not require any medium and can be used for the transfer of heat in a vacuum as well. This method uses electromagnetic waves which transfer heat from one place to the other. The heat and light from the sun in our solar system reach our planet using radiation only.
In fact, radiation is the most potent method of heat transfer. In winters when we sit near a fire we feel warm without actually touching the burning wood. This is possible by radiation only.
