Why Does The Sun Give Of Light? - Answers
WebSo the Sun doesn't give off any gamma rays to speak of. The Sun does, however, emit x-rays, UV, light (of course!), IR, and even radio waves. The peak of the Sun's energy output is actually in the visible light range. This may seem surprising at first, since the visible region of the spectrum spans a fairly narrow range. WebThe light (photons) are by product of a nuclear reaction going on inside the sun. In this nuclear reaction, hydrogen atoms fuse together to become helium atoms. This reaction occurs at the core (center) of sun under immense gravitational pressure at the core due to all the mass of the sun.
