【分析解答题】

The nuclear energy is released at the Sun’s center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very’ much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun, to/be re-emitted at slightly longer wavelengths. This radiation, in its turn, is absorbed and re-emitteD、As the energy filters through the layers of the solar interior, it passes through the X-ray part of the spectrum, eventually becoming light.At this stage, it has reached what we call the solar surface, and can escape into space, without being absorbed further by solar atoms.

A、very small fraction of the Sun’s light and heat is emitted in such directions that, after passing unhindered through interplanetary space, it hits theEarth.
