What is the emission spectrum of the sun and what does this spectrum reveal about the types of elements in the sun?

The emission spectrum of the sun is primarily a continuous spectrum with dark absorption lines, known as the Fraunhofer lines, which occur at specific wavelengths where elements in the sun's atmosphere absorb light. This spectrum reveals the presence of various elements, including hydrogen, helium, calcium, and iron, as each element absorbs light at characteristic wavelengths. By analyzing these absorption lines, scientists can determine not only the composition of the sun but also its temperature, density, and other physical properties. Overall, the sun's emission spectrum serves as a crucial tool in astrophysics for understanding stellar composition and behavior.
