Answer 1

What is the nature of radiation generated in the Sun’s interior?

The Sun, like all stars, is able to create energy during fusion reaction. On the Sun, there are two zones with different types of energy transport: the radiative zone and the convective one. In the radiative zone, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. In the convective zone, heat and energy are carried outward along with matter in swirling flows called convection cells.

How does it differ from the radiation we receive from the Sun?

The photosphere is a star’s outer shell from which light is radiated. In our case, photosphere is the visible surface of the Sun. The energy from the Sun is conveyed by photons. In addition to producing light in the form of gamma-rays, other particles such as neutrinos are produced. The energy emitted from the photosphere of the Sun then propagates through space and reaches Earth’s atmosphere and the other planets of the solar system. The upper layer of the atmosphere (the ozone layer) filters much of the Sun’s ultra-violet radiation, but passes some onto the surface.
