## Superposition Exercise #6

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

#### Description

A particle is in a one-dimensional box of length a=1. It
is in a normalized superposition of two states. There is an equal amount
of each state. Shown is Psi^{ }and the results of the integrals
that give <p> and <p^{2}> (in units of hbar and hbar^{2}.

Vary n_{1} and n_{2} keeping n_{1}<n_{2}
to avoid double counting and also avoid n_{1}=n_{2}. Vary the quantum
numbers from 1 to 10.

#### Questions

- What do you notice about <p> and <p
^{2}>? Do your
results differ from the states that were not a superposition of states?
- For n
_{1} = 1 n_{2} = 2, what is Dp?
