What is photosphere?
It is the visible surface of the sun.
The photosphere is the visible surface of a star, such as the Sun. It consists of a zone in which the gaseous layers change from being completely opaque to radiation, to being transparent. For example, the photosphere of the Sun is the layer from which the light we actually see (with the human eye) is emitted.
The lowest layer of the sun"s atmosphere and the layer from which light is given off is the photosphere.It is also called the surface of the sun.Its temperature is about 6,000k.Above the photosphere is the chromosphere.Its layer extends upward about 2,000 km above the photosphere. by:Marina Tamang of I.S125.
The sun's atmosphere has three layers: the photosphere, the chromosphere, and the corona. The lowest region, the photosphere, is what we see as the surface of the sun. The chromosphere surrounds the photosphere. The corona is the final layer, extending millions of miles out from the others and being seen from Earth best during a solar eclipse.
