n=5 S? n 1 n= n=4 n=3 n = 2 n = 1 -0.545 ev -0.849 ev -1.51 ev -3.41 eV -13.60 eV Refer to the diagram for question 12.22. Plot a graph of the values of energy E on the y-axis against the square of the number of the level (i.e. n) on the x-axis. Choose scales so that values of n up to 60 can be plotted on the x-axis, and use a scale of 1 cm per eV on the y-axis. From your graph deduce the next two highest energy levels above those shown in the previous diagram.
