Explain why the Sun’s light produces more absorption lines than a light bulb or fluorescent lights
Where do elements in the Sun’s atmosphere come from? Explain your answer in detail.
The sun is a middle-aged star. If you could analyze the light from a much older star, what would you expect to see? Think about the products of nuclear fusion. Does fusion stop at helium?
Why might we be interested in oxygen and water’s absorption lines when looking for exoplanets?
Answers
Answer:
Because sun is at infinity so sun produces more absorption lines than a light bulb.
Sun is composed of gases and plasma hence such elements were there already. Sun is not a definite star. It melt what comes in it way.
No fusion doesn't stop at helium
Because water and oygen are essential compounds to survive
Answer:
1. Answer:- A light bulb converts electricity to photons. ... Vastly more energy comes from the sun than from any artificial light. But the light from the sun is different from a street lamp another way: most artificial light doesn't emit as much energy in the red and blue region of the light spectrum as sunlight does.
2. Answer:- The process of nuclear fusion combines hydrogen atoms to produce helium and the energy that keeps the Sun shining. The next three elements heavier than helium — lithium, beryllium, and boron — are sometimes formed as intermediate products during the fusion process .
3. Answer:- Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. ... DT fusion produces a neutron and a helium nucleus.
If The Nuclear Fusion Is Stops In Sun There Is No Any Source Of Energy In The Earth And Many Causes And Deserter Comes In Living Organism And All Species Are Going To Be Extinct .
4. Answer :- There are lots of reasons to learn about exoplanets, but perhaps the most compelling is that we could find another world that hosts living organisms. If we discover life beyond Earth, it could change the course of human history.
