Why does the helium spectrum have more lines? Answer and Explanation: Helium has more spectral lines than hydrogen. WebAnswer: Yes, the helium does line up with the star spectrum Instructions: Drag the helium spectrum next to the star spectrum. Do some lines match? Based on the experiment , upon dragging the helium spectrum next to the star spectrum, we can observed that the helium does line up with the star spectrum 4.
