Excitation and deexcitation: Day 1, P1
Atoms Can be Excited
page 3 of 6
1. Here is how the game of Atomic Billiards works: you can give the pink atom different velocities by adjusting the slider.* When you click on the Run button, the atoms will collide and the graph will reflect any changes in kinetic energy.
2. Experiment with giving the pink atom different velocities. See how much you can observe by watching changes in the vectors and changes in the graphs.
3. Click the "snapshot" button if you observe any new behavior that occurs only when you change the velocity. Describe in the area for text in the snapshot just what you observed.
*Really you are creating different atoms by changing the energy levels.
