Detailed explanation-1: -The photosphere is the lowest layer of the sun’s atmosphere-the innermost layer we can observe directly. The term photosphere means “sphere of light” and is the layer where most of the sun’s energy is emitted. It takes about eight minutes for sunlight from the photosphere to reach Earth.
Detailed explanation-2: -In the chromosphere, almost all the mechanical energy flux supplied to the outer solar atmosphere by magneto-convection is converted into heat and radiation, leaving a small amount to power the solar wind and the hot corona: the chromosphere requires over 30 times more energy than the corona and heliosphere combined.
Detailed explanation-3: -A “Dancing” Layer of the Sun Above the photosphere is a layer of gas, approximately 2000 km thick, known as the chromosphere or sphere of color. In the chromosphere energy continues to be transported by radiation. Hydrogen atoms absorb energy from the photosphere and most of the energy is then emitted as red light.
Detailed explanation-4: -The chromosphere is a thin layer of plasma that lies between the Sun’s visible surface (the photosphere) and the corona (the Sun’s upper atmosphere). It extends for at least 2, 000 km (1, 200 mi.) above the surface.
