What Is In The Chromosphere?

The most visible and impressive features of the chromosphere include filaments and prominences. These gigantic plumes of gas are trapped by magnetic fields above the photosphere, reaching altitudes of 150,000 km above the Sun.

What is the chromosphere of the Sun composed of?

Why does the chromosphere shine so brightly in the color red? Composed mostly of hydrogen, under these temperature conditions, the most common way that hydrogen gases shine is through the emission of a particular spectral line called hydrogen-alpha or Ha at a wavelength of 656.3 nanometers (6563 Angstroms).

How do astronomers detect structure in the chromosphere?

How can astronomers detect structure in the chromosphere? Ans: The structure of the chromosphere is studied primarily using filtergrams. Filtergrams are images of the sun taken through a filter that lets in a very narrow wavelength band of light, such as light emitted by the Hydrogen-alpha transition.

What is the chromosphere of a star?

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. … The chromosphere, thus, can be only seen during a complete solar eclipse.

What does the chromosphere contribute to the solar spectrum?

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.

Where is the chromosphere of the Sun quizlet?

Where is the chromosphere on the Sun? It is the layer above the visible surface of the Sun.

How hot is the chromosphere?

the chromosphere is the innermost atmospheric layer. It is just above the photosphere. Here the temperature begins to rise again, to about 36,000 degrees F. Above the chromosphere is the transistion layer, where temperatures increase 6000 to over half-a-million degrees.

What interesting features does the chromosphere have?

The chromosphere is a thin layer, about 2,000 to 3,000 kilometers (1,243 to 1,864 miles) thick. Its temperature is 6,000 to 50,000 degrees Celsius (10,800 to 90,000 degrees Fahrenheit), increasing with altitude. Scientists speculate that the temperature increases with altitude due to magneto-hydrodynamic waves.

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.

Which structure of the Sun refers to a highly tenuous region over the chromosphere?

The Chromosphere – This relatively thin layer of the Sun is sculpted by magnetic field lines that restrain the electrically charged solar plasma. Occasionally larger plasma features, called prominences, form and extend far into the very tenuous and hot corona, sometimes ejecting material away from the Sun.

What is chromosphere physics?

The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission). … This is what gives the chromosphere its name (color-sphere).

Where is the chromosphere?

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 is the chromosphere and when can it be seen?

The chromosphere, thus, can be only seen during a complete solar eclipse. … It is the H-alpha emission which actually gives the chromosphere its reddish colour. The red rim can be seen when this H-alpha burns at a high temperature during a total solar eclipse.

What is another name for the chromosphere?

Find another word for chromosphere. In this page you can discover 5 synonyms, antonyms, idiomatic expressions, and related words for chromosphere, like: photosphere, solar-corona, outer-atmosphere, mesosphere and aurorae.

How thick is the chromosphere?

The chromosphere is about 2000 km thick. We only see this layer and the other outer layers during an eclipse. The corona extends outwards for more than a solar radius.

What is the eruption of gases from the chromosphere?

Solar flares are sporadic local eruptions of the chromosphere. They develop suddenly and rapidly, in minutes, and cover a relatively small region of the solar surface. Initially they manifest themselves by a localized sudden brightening. The duration of a solar flare ranges from about 20 minutes to as much as 3 hours.

Why is the chromosphere pink?

The chromosphere represents the dynamic transition between the cool temperature minimum of the outer photosphere and the diffuse million-degree corona above. It derives its name and pink colour from the red Hα line of hydrogen at 6562.8 angstroms (Å); 1 Å = 1010 metre.

What is the chromosphere quizlet?

chromosphere. It is a thin, hot layer of gas just above the photosphere. Most easily visible during total solar eclipses, when it flashes into view for a few seconds. You just studied 13 terms!

What is the chromosphere of the Sun quizlet?

Definition: The chromosphere is outside of the photosphere and is approximately 2,500 km thick and has a temperature of nearly 30,000 Kelvin. Sentence with extra information: The chromosphere is visible only during a solar eclipse when the photosphere is blocked.

Is the chromosphere hotter than the 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 type of spectrum is produced by the chromosphere?

It appears just as the line absorption spectrum of hydrogen-alpha of reddish color with wavelength 656.3 nm. ∴ The spectrum obtained from the chromosphere of the sun at the time of the total solar eclipse is the line absorption spectrum.

How can you identify the chromosphere during a total solar eclipse?

How can you identify the chromosphere during a total solar eclipse? It’s a reddish glow at the end or beginning of an eclipse. Why can you see the corona during a total solar eclipse? Because the moon blocks out the glow of the photosphere.

What does chromosphere mean in English?

: the region of the atmosphere of a star (such as the sun) between the star’s photosphere and its corona.
