Mg emits radiation at 285nm could a spectroscope be used to detect this emission?

Answer 1

285nm is ultraviolet, and I think with a spectroscope you actually look with your eye to see the emission - you would not be able to see this wavelength. If you put some kind of a film that reacts to UV light in the spectroscope, you could then "see" it as a mark on the film.

Answer 2

Yes, a spectroscope could be used to detect the emission of radiation at 285nm. A spectroscope separates light into its different wavelengths, allowing the specific wavelength emitted by Mg (285nm) to be measured. This can help identify the presence of Mg based on its unique spectral emission line.
