Mg emits radiation at 285 nm could the spectroscope be used to detect this emission. Explain.
Also if you know this questions it would be great...
If Boron emits radiation at 518 nm what color will Boron impart to a flame.

285 nm is beyond the ability of people's eyes to see (it is in the UV region) possibly it could be observed if the spectrometer was connected to some kind of UV-sensitive detector instead of your eye.
The color from boron is green

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.
518nm is greenish
