The three main parts of the Sun are the core, radiative zone, and convective zone. The core is where nuclear fusion occurs, producing the Sun's energy. The radiative zone is where energy is transported by electromagnetic radiation, and the convective zone is where energy is transported by convection currents.
From the Sun's core, energy moves through the radiative zone, across the tachocline (transition layer) to the convective zone, and then to the outer convective zone with its visible granulation.
The Sun's radiative zone is the section of the solar interior between the innermost core and the outer convective zone. In the radiative zone, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. In other words, the energy is conveyed by photons. When the energy reaches the top of the radiative zone, it begins to move in a different fashion in the convective zone. In the convective zone, heat and energy are carried outward along with matter in swirling flows called convection cells. This motion is similar to the roiling flows seen in a pot of boiling water. The inner parts of the Sun (core and radiative zone) spin differently than the outer layers (convective zone). The boundary between these two types of rotation, which lies between the radiative and convective zones, is called the tachocline. Many other stars also have radiative zones. The Sun's radiative zone extends from the core outward to about 70% of the Sun's radius. In a smaller (than the Sun) star that is cooler than our Sun, the convective zone tends to be larger, extending deeper into the star's interior. Thus the radiative zone tends to be smaller. In very small, cool stars the convective zone may reach all the way to the star's core, and there may be no radiative zone at all. In a larger (than the Sun) star with a higher temperature, the radiative zone tends to be larger and the convective zone smaller. Especially large, hot stars may not have a convective zone at all - their radiative zone may extend all the way from the core to the star's surface.
In the radiative zone of the sun, energy moves through the transfer of photons. Photons, which are massless particles of light, are created through nuclear fusion in the sun's core and gradually travel through the radiative zone, bouncing off particles in a zig-zag pattern until they reach the convective zone.
Hi! It's 13 Million* Fahrenheit to 3.6* Fahrenheit.
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.

The radiative zone is where energy is transported by electromagnetic radiation, and the convective zone is where energy is transported by convection currents.
The radiative zone of the Sun is not visible to the human eye, so it does not have a color. It is located beneath the Sun's visible surface where energy is transported by photons through a process of radiative diffusion.
They are the Convection Zone, Radiative Zone, then the Core.

The core, the radiative zone, and the convective 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.
From the Sun's core, energy moves through the radiative zone, across the tachocline (transition layer) to the convective zone, and then to the outer convective zone with its visible granulation.

The layer of the Sun through which energy is transferred away from the core by radiation is called the radiative zone. In this zone, energy from the core travels outward as photons, which are absorbed and re-emitted multiple times by the particles in the dense solar plasma before reaching the convective zone.
