The sun generates a wide range of electromagnetic (EM) spectrum, primarily through hydrogen fusion and other reactions influenced by its intense magnetic field. White light is perceived as a combination of all visible frequencies, and the sun emits this light unevenly across the spectrum. Pulsars and black holes primarily emit in the radio range due to synchrotron radiation from their compressed magnetic fields, while gamma and X-ray emissions result from the heat and friction of infalling matter. The temperature of a star correlates with the breadth of its spectrum, with hotter stars producing whiter light. Overall, the sun's emissions reflect complex processes beyond simple fusion reactions.
