Answer to Question 1
Answer: Although the peak emission of solar radiation is in the visible portion of the spectrum, the Sun emits radiation across the full range of the spectrum from gamma rays to radio waves.
Answer to Question 2
Answer: In the innermost portion of the Sun consists of its core, the radiation zone, and the con- vection zone. The core, is characterized by extremely high temperatures (about 15 million C, or 27 million F) and high densi- ties lead to the energy-generating process of nuclear fusion. Energy initially travels outward from the core as electromagnetic energy through the radiation zone and into the base of the convection zone, where upwelling of the solar gases transfers the energy to the relatively thin solar surface. The layer of the Sun that radi- ates most of the energy away from the Sun is called the photosphere. It is the layer of the Sun we actually see as the solar disk.
