Electromagnetic radiation from sun is more likely produced by the nuclear fusion, and at a go radiation is released but how is it possible for different types of radiation to be produced such as, gamma, x-rays, UV, visible light, infrared, microwaves, and radio waves?

Please answer, and let me know, if my question makes sense or if I have any mistakes. In the answer please try to use least possible math, I'm just a high school student.

Nuclear fusion is the main source of solar energy, but no the only source of how this energy is converted into radiation. Thus,

  • gamma rays are mainly emitted as a result of nuclear reactions
  • ultraviolet, infrared, and optical waves are mainly result of relaxation processes within atoms
  • X-rays are result of Bremsstrahlung, i.e., acceleration or deceleration of charged particles
  • radiowaves are a result of "slow" oscillations of masses of charge

In fact, there is a lot of overlap between these process - e.g., nuclear reactions can also emit radio wave radiation (e.g., see here) - I indicated just the dominant outcome.
