Unformatted text preview: 17:32 Nov 15, 2011 question A which of the following represents density of the sun from the core to the photosphere. D Nuclear fusion in the core of the sun generates gamma-ray photons the sun is so dense, it can take hundreds of thousands of years for the photons to reach the photosphere by the time photons escape, their energies form a blackbody spectrum with a temperature of about 5,000K question a high energy photon is produced by a nuclear reaction at the enter of the sun, which diagram best represents how that photons energy escapes from the suns radiatve zone C photons bounce around randomly insde the sun making their way outwards in the radiation zone, photons carry energy from the deepest layers to the upper layers in the upper layers of the material is cooler and less dense in the convection zone, hot gas rises and cooler gas sinks carrying heat to the surface the surface of the sun is like a thick fog with hot material rising and cool material sinks...
