Is sun a black body radiation and can we say that the Sun contains charges that produce electromagnetic wave?
The Sun is not a perfect black body, but it is a good approximation. This means that its spectrum is close to that of a black body, which is a hypothetical object that absorbs and emits all radiation perfectly. The Sun's spectrum peaks in the visible range, but it also emits radiation in the ultraviolet, infrared, and radio wavelengths.
The Sun's energy is produced by nuclear fusion, which is a process in which hydrogen atoms are combined to form helium atoms. This process releases a tremendous amount of energy, which is what heats the Sun and causes it to emit radiation.
The Sun's radiation is constantly bombarding the Earth, and it is this radiation that provides the energy for life on Earth. Plants use sunlight to produce food, and animals eat plants to get the energy they need to survive. The Sun's radiation also warms the Earth's atmosphere, which makes it possible for liquid water to exist on the surface of the planet.
In addition to providing energy for life, the Sun's radiation also has other important effects on the Earth. The Sun's ultraviolet radiation can damage DNA, which can lead to skin cancer. The Sun's radiation can also cause electrical storms and magnetic field disturbances.
Despite the risks, the Sun is essential for life on Earth. Without the Sun's radiation, the Earth would be a cold, barren planet.
The Sun is a hot plasma fireball. It may be astrophysically assumed to behave as a black body for analytic simplicity, but astronomically not, as per observations. It is evident from the literature that the solar (stellar) surface boundary (non-rigid potential interface between its interior and exterior) is indeed electrically charged.
The Sun emits at almost all wavelengths of electromagnetic radiation but 99% of the emitted radiation is in the ultraviolet, visible, and infrared regions. The Sun is a nonideal blackbody, emitting more radiation than expected in the X-ray and far-UV as well as the radio regions of the spectrum. As with all matter, the sun emits a “black body spectrum” that is defined by its surface temperature. A black body spectrum is the continuum of radiation at many different wavelengths that is emitted by anybody with a temperature above absolute zero. It absorbs all the incident radiation falling on it and does not transmit or reflect regardless of wavelength and direction. It emits the maximum amount of thermal radiation at all wavelengths at any specified temperature. Blackbody radiation is a term used to describe the relationship between an object's temperature, and the wavelength of electromagnetic radiation it emits. A black body is an idealized object that absorbs all electromagnetic radiation it comes in contact with. The Sun is made of plasma, which is a gas of bare ions and electrons. The energy released from nuclear fusion heats this plasma, and the moving charges emit electromagnetic waves. All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Electromagnetic radiation is generated by the vibration of electrons or other electrically charged particles. The energy produced by this vibration travels in the form of electromagnetic waves. The sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior, where temperature and pressure are extremely high. During most of the sun's life, energy comes from the fusion of hydrogen nuclei. When a charge particle falls in electric field the velocity of charge particle changes so its motion becomes accelerated and can produce EM wave. It verifies answer (d) An electromagnetic wave can be created by accelerating charge.
