Suppose you're experimenting with the spectrum produced by heated hydrogen gas. If you double the quantity of hydrogen and examine the resulting spectral lines, what is most likely to have changed? Group of answer choices   The number of lines seen.   The frequencies of the lines.   The intensity of the lines.   The pattern made by the lines.   The wavelengths of the lines.

Change in energy and wavelength 1st peak (Start from right) Red region 2nd peak Light blue-green region 3rd peak Blue-purple region 4th peak Dark purple region Wavelength (nm) 656.6 485.3 436.6 409.7 no 2 2 2 n₂ Ephoton (J) Table view List view Eone mole photon (kJ/mol)
