Let's plot that for different values of n.

Remember, n is a natural number. Natural numbers start with 1 and

go up, 1, 2, 3, 4, 5. In order to do this, as I have been doing

throughout the course, I'm going to plot energy On the y axis.

In this case, the energy's a little bit more complicated because

I've taken out that factor of Planck's constant and Rydberg's constant.

And the next thing I'm going to do is plot

minus 1 over n squared for a bunch of different values.

Notice that 0 is up at the top of this graph.

So all the numbers I'm going to be plotting are negative numbers.

The first number I'm going to plot is minus 1 over 1 squared.
