What are the photosphere and chromosphere?

What are the photosphere and chromosphere?

Photosphere – The photosphere is the deepest layer of the Sun that we can observe directly. Most of the photosphere is covered by granulation. Chromosphere – The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere).

What are the photosphere chromosphere and corona?

The Sun – our central star Beginning from the outside, they are: the corona – the outermost, hot shell of the atmosphere. the chromosphere – a transparent layer between the corona and the photosphere. the photosphere – the visible “surface” of the Sun.

Which is hotter chromosphere or photosphere?

While the photosphere hovers around 5,800 kelvin, the temperature of the chromosphere varies between 4,500 K and 20,000 K. Even though it’s more distant from the center of the Sun, the chromosphere is hotter than the photosphere. It has a reddish color, but you can only really see it during a total solar eclipse.

What comes first chromosphere or photosphere?

The chromosphere is above the photosphere, the visible “surface” of the Sun. It lies below the solar corona, the Sun’s upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density.

What does the chromosphere do?

The sun’s chromosphere But the red rim can only be seen during a total solar eclipse. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.

Why is it called the chromosphere?

It is actually the transition between corona and the photosphere. Out of the three layers of the Sun’s atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third). Description: As the name suggests, chromosphere literally translates into ‘sphere of light’.

Is corona and chromosphere the same?

It is called chromosphere because it has a red to pink colour. It is normally only visible during a solar eclipse. The corona is plasma surrounding the Sun which extends hundreds of kilometers from the surface of the Sun. It is much hotter than the surface of the Sun with temperatures reaching 3,000,000K.

What is the difference between corona and photosphere?

Definition: Chromosphere is a reddish and glowing layer of gas above a star’s (or Sun’s) photosphere. It is actually the transition between corona and the photosphere. Out of the three layers of the Sun’s atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third).

What is the function of the chromosphere?

The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.

Why chromosphere is red?

A wavelength of 656.3 nm is in the red part of the spectrum, which causes the chromosphere to have its characteristic reddish colour. By analysing the spectrum of the chromosphere, it was found that the temperature of this layer of the solar atmosphere increases with height in the chromosphere itself.

What does the chromosphere look like?

Comparing chromosphere and photosphere By analysing the spectrum of the chromosphere, it was found that the temperature of this layer of the solar atmosphere increases with height in the chromosphere itself.
