Classical and Quantum Particle in a Harmonic Oscillator
## Classical / Quantum Exercise #2

#### Please answer the following 2 questions
regarding the Physlet:

1. Click on "Start Quantum Graph" below the right-hand graph.
The graph shows the probability that a particle is in the ground state at some
position x. You may vary n to see higher energy states. Under the
left-hand graph, a ball is oscillating back and forth on a spring. What does the probability
of finding the particle as a function of x look like? Why?
After you answer, click "start Classical Graph" and check yourself. Was your answer right
or wrong?

2. Under what conditions would the right-hand graph look like the left-hand
graph. In other words, what is the correspondence between the classical and quantum
position probabilities of a
particle undergoing simple harmonic motion? Check your answer using the above
"Start" buttons.
