1. The problem statement, all variables and given/known data I have two graphs (Radiant Power vs wavelength) and I have to choose which one would be the best for a shop -- the one with the least yellowing. (fluorescent bulbs) I wasn't sure how to tell. The emission spectrums are very similar. The continuous spectrums are different, the one has a wider radiant power in the 350-500 wavelength (in nm) and the other has more in the 600-700 wavelength part. They have about the same from 550 to 590 nm. 3. The attempt at a solution I think the one with the greater wavelength from 400 - 600 nm would be the whitest, without a yellowing effect because it has more blue-green-yellow of the spectrum to make white, while the other has more of the end of the spectrum, indicating a more yellowish light. Is this the right way to go about choosing the light? Any help is highly appreciated, thank you!
