Question

The star P Cygni in the constellation Cygnus the swan is surrounded by an extensive, low-density atmosphere. The spectrum of P Cygni shows a bright continuum with many narrow, dark absorption lines and a few bright emission lines. Make a rough sketch of P Cygni in the space below and indicate where the light that forms the absorption lines comes from and where the light that forms the emission lines comes from.

Answer 1

he same event exists in the star and the nine the nine absorbs the respective wavelength giving rise to the so-called absorption spectrum.

When there is an element in the star that is not in the nine, radiation passes through the nine giving rise to the so-called emission spectrum.

Step-by-step explanation:

The star emits a series of lines depending on the elements that make it up, this radiation is emitted into space and interacts with the gas cloud that surrounds the alien.

When the same event exists in the star and the nine the nine absorbs the respective wavelength giving rise to the so-called absorption spectrum.

When there is an element in the star that is not in the nine, radiation passes through the nine giving rise to the so-called emission spectrum.
