10.3 Radiation

This section covers the following syllabus (Physics 5059) requirements.

  • explain that energy transfer of a body by radiation does not require a material medium and the rate of energy transfer is affected by:

(i) colour and texture of the surface

(ii) surface temperature

(iii) surface area

  • apply the concept of thermal energy transfer (radiation) to everyday applications
Explain that energy transfer of a body by radiation does not require a material medium and the rate of energy transfer is affected by colour and texture of the surface, surface temperature and surface area.. Apply the concept of thermal energy transfer (radiation) to everyday applications.
