Final answer:
Without the spectral data provided, we cannot determine which compound would match the spectrum in question. Different light sources examined with a spectrometer would yield a variety of spectra, depending on their characteristics and the gases or materials they contain.
Step-by-step explanation:
The student's question appears to be asking about the identification of a compound based on its spectral data. However, without the actual spectrum provided in the question, it's impossible to determine which compound (Compound A, B, C, or D) would have yielded the spectrum.
When examining spectra, scientists often look for characteristics such as peaks and troughs that correspond to specific molecular bonds or functional groups.
For example, in infrared (IR) spectroscopy, different types of chemical bonds absorb IR radiation at different frequencies.
These absorptions can be seen as peaks in an IR spectrum, and the position of these peaks (usually measured in wavenumbers, cm⁻¹) can help identify functional groups present in a molecule.
As for the other questions mentioned, looking at various light sources with a spectrometer would yield distinctive spectra depending on the source.
A household lightbulb typically shows a broad spectrum; the Sun would give a continuous spectrum with some absorption lines (Fraunhofer lines); neon lights show emission lines characteristic of noble gases; an ordinary flashlight would exhibit a spectrum based on the type of bulb (LED or incandescent); and a streetlight may show either broad or line spectra based on its light source (sodium vapor, LED, etc.).
