Does it take a long time or a short time for gamma rays to reach the photosphere

  1. Apr 23, 2010 #1
    What happens to gamma rays as they travel outward from the core of the sun through the sun?

    -also, does it take a long time or short time for neutrinos to reach the photosphere of the sun from the core of the sun? Why?

    The main question has nothing to do with the earth, it is more specifically, does it take a long time or a short time for gamma rays to reach the photosphere of the sun originating from the core of the sun

    Don't know how reliable this source is:
    http://solar.physics.montana.edu/ypop/Spotlight/SunInfo/Radzone.html

    but apparently it takes about 170 000 years for energy from the core to get through the radiative transfer zone alone. It now has to get through the convection zone, although according to the same source, this only takes something like a week or so.

    But if these numbers are important to you, try to find other sources than this simple tutorial to confirm.
