11.3 Heat Transfer through Radiation

The Sun serves as the main source of heat for our planet. However, this heat does not reach the Earth through conduction or convection, as there is no medium between the Sun and Earth's atmosphere. Instead, heat is transferred via radiation, a process in which energy travels across space in the form of electromagnetic waves.

In radiation, heat transfer occurs through electromagnetic waves without requiring a medium.
