Question

    The energy emitted by the Sun is due to

    A Chemical reaction Correct Answer Incorrect Answer
    B Nuclear fission Correct Answer Incorrect Answer
    C Nuclear fusion Correct Answer Incorrect Answer
    D All of the above Correct Answer Incorrect Answer

    Solution

    The spectrum of the Sun's solar radiation is close to that of a black body with a temperature of about 5,800 K. The Sun emits Electromagnetic radiation across most of the electromagnetic spectrum. Although the Sun produces Gamma rays as a result of the nuclear fusion process, these super high energy photons are converted to lower energy photons before they reach the Sun's surface and are emitted out into space.
