I'm having trouble figuring this out. I've read, that when photons are created via nuclear processes inside a star, it can take about 1 million years for photons to actually reach the surface of a star, due to the "random walk" motion inside the stars interior. But in our Sun, the core is radiative, and the outer layers are convective. Does that mean, that when the photons reach the bottom of the convective layer, they can't go any further, or are they somehow transported by convection, so they don't do their "random walk"?
Don't know if my question is clear. I'm just confused about what happens with the photons when there is a change from radiative to convective zones.
