What is the purpose of a spectrometer?

• A. To amplify sound waves in experiments
• B. To measure the distance of celestial bodies
• C. To measure properties of light across the electromagnetic spectrum
• D. To visualize the spectrum of sound waves

Answer: (C)

The purpose of a spectrometer is to measure properties of light across the electromagnetic spectrum, which is essential in various scientific fields such as physics, chemistry, and astronomy. A spectrometer works by splitting light into its constituent colors or wavelengths, allowing for the analysis of the intensity and distribution of light across these wavelengths. This analysis can reveal critical information about the composition, temperature, density, and motion of the material emitting or reflecting the light. Different types of spectrometers, like mass spectrometers or optical spectrometers, are used depending on the specific properties being investigated. The other choices, while related to different fields of study, do not accurately describe the function of a spectrometer. Amplifying sound waves pertains to acoustics and is not related to light measurement. Measuring distances to celestial bodies involves astronomical techniques such as parallax or radar ranging, rather than spectroscopy. Lastly, visualizing the spectrum of sound waves is a matter of signal processing in acoustics rather than the analysis of light, which is the primary function of a spectrometer.
