Question

e: lt is recommended that you save your response as you complete each question. estion 1 (2 points) The photosphere of the the sun produces an absorption spectrum because: A) The density of the upper layers is much less than the density of the lower layers. B) The density of the upper and lower layers are almost exactly the same. C) The density of the upper layers is much higher than the density of the lower layers. Save uestion 2 (2 points) During a solar eclipse the Sun's chromosphere can be seen and light from it analysed. Which the following observations of its spectrum supports the idea that it is composed throughout

Explanation / Answer

The density of upper layer is much less than the density of lower layer. The top of the photosphere is significantly cooler, with a temperature of only 4400 Kelvin; thus, the cooler, low-density gas at the top of the photosphere produces absorption lines in the solar spectrum.

Its spectrum is of emission type. During a total solar eclipse, an exceptional situation occurs, and for a few fleeting seconds, an emission spectrum can be observed.
