Radiation
What this topic asks you to be able to do
- Describe how thermal energy is transferred by infrared radiation, and understand that such transfer does not need a medium.
- Describe how the colour of a surface (black or white) and its texture (dull or shiny) affect how much infrared radiation it emits, absorbs and reflects
- Describe how an object's surface temperature and surface area affect the rate at which it emits radiation
- Describe experiments that distinguish good emitters of infrared radiation from bad ones.
- Describe experiments that distinguish good absorbers of infrared radiation from bad ones.
