You will make a graph of your data from the helium spectrum. What purpose will it serve in the data analysis? O It will allow us to calculate the energies of the lines in the helium spectrum based on their wavelengths. O It will allow us to calculate the energies of the lines in the hydrogen spectrum based on their wavelengths. O It will allow us to calculate the wavelengths of the lines in the helium spectrum based on their positions. O It will allow us to calculate the wavelengths of the lines in the hydrogen spectrum based on their positions. O It will allow us to calculate the colors of the lines in the hydrogen spectrum based on their times.
