ReneRadiative exchange refers to the transfer of heat through electromagnetic radiation between two surfaces at different temperatures. This process can occur in a vacuum and does not require a medium for heat transfer. The rate of radiative exchange is dependent on the temperature and emissivity of the surfaces involved.

How do the temperatures of the radiative zone and the convection zone compare?
The radiative zone is hotter than the convection zone. In the radiative zone, energy is transferred through electromagnetic radiation, while in the convection zone, energy is transferred through the movement of hot gas or plasma.
When is an object in radiative balance?
An object is in radiative balance when it absorbs the same amount of radiation as it emits. This equilibrium results in a steady temperature for the object.
How thick is the layer of the radiative zone?
The radiative zone extends from the outer edge of the solar core to about 70% of the distance to the solar surface. It is approximately 200,000 kilometers thick.
How long does does it take photons to cross the radiative zone?
Oh, dude, photons are like the rockstars of the Sun, cruising through the radiative zone at the speed of light. It takes them about a million years to make their way from the core to the convective zone. So, you know, just your average cosmic commute.
In which layer of the sun is energy transferred between?
The convection zone.
