Years ago a high school physics teacher put some gas tubes into storage but forgot to label them. Now the school needs to figure out what kind of gas is in each tube. The spectrum from one of the tubes is shown below: A [mm] a) Is this an emission, absorption, or continuous spectrum? How is this particular spectrum made? b) The teacher is certain that the gas is either hydrogen or mercury. Use the energy level diagrams given below for each type of gas to determine the type of gas that gave off the spectrum shown. Show your work and explain your understanding. Hydrogen Mercury Level Energy (eV) Level Energy (ev) Ionization- -0.38 -0.54 n=4 -0.85 n = 3 -1.51 Ionization- 0.00 n = 2 -3.40 .56 1.57 2.48 .68 3.71 .95 -5.52 -5.74 Ground State - Ground State- n = 1. -13.60 -10.38 Energy Levels for the Hydrogen Atom A Few Energy Levels for the Mercury Atom
