WebbDefinition of the Photosphere. As we look down into the atmosphere at the surface of the Sun the view becomes more and more opaque. The point where it appears to become completely opaque is called the photosphere. Thus, the photosphere may be thought of as the imaginary surface from which the solar light that we see appears to be emitted. Webb13 apr. 2024 · Furthermore, on the Sun, B g is generated by external currents below the photosphere. Therefore, small values of n g may not be realizable on the Sun either.

If we could look at the Sun directly (never stare at the Sun without the proper equipment) we would see the photosphere. WebbThe Photosphere is around 500 km thick, and this is the layer where most of the Sun’s radiation and rays finally escape, and this is also where sunspots happen.
