Light from a distant star is analyzed and found to contain high intensities of light at the following wavelengths: 706, 656, 587, and 502 nm . What elements are present in the star?

Q: Expert Answer

Interpretation Introduction Interpretation: The elements present in the star are to be identified. Concept Introduction: Absorption spectroscopy is a technique of measurement of the absorption of radiation. The color of any substance depends on the color of the light absorbed by the molecules or atoms that compose the substance. Absorption spectroscopy is very useful in distinguishing many chemical compounds from each other in a mixture. The specificity of spectroscopy allows one to identify the unknown samples by comparing with the reference spectra. Explanation Given information: Wavelengths of intensities of light are 706, 656, 587, and 502 nm . In any substance, when atoms or molecules absorb certain wavelengths of light, they reflect the color of the light which is not absorbed. When an atom or molecule absorbs light, the electrons get excited from a lower energy level to a higher energy level, during which they release the energy in the form of radiation. The electromagnetic spectrum is the range of all types of radiation

Explanation of Solution

Given information: Wavelengths of intensities of light are 706, 656, 587, and 502 nm.

In any substance, when atoms or molecules absorb certain wavelengths of light, they reflect the color of the light which is not absorbed. When an atom or molecule absorbs light, the electrons get excited from a lower energy level to a higher energy level, during which they release the energy in the form of radiation.
