Discuss/describe two examples where emission or absorption spectroscopy is used.

Pick one of the questions below to answer. Be very careful not to pick the same question that any of the other students assigned to post on this topic did – or you will not get credit!(1) Which of the following elements (Li, Cs, K, Na, Rb) are in the Unknown Spectrum shown below? Be sure to check the side-by-side comparison link below. Hint: sometimes there is not enough energy available for all of the lines to be visible. If you see any of the spectral lines of an element, then that element is present.(2) Why does each element have a unique pattern? Answer in your own words. Be as detailed as needed and include where you found your information.(3) Discuss/describe two examples where emission or absorption spectroscopy is used. One example should be for something here on Earth (i.e. analysis of soil, water, or air), and the other for analyzing composition of something in space. Answer in your own words.Check the side-by-side comparison link below(Hint: if you see any of the spectral lines of an element, then that element is present)see attached picture.
