Section 21.1 States on a Ring

The applet below displays the real and imaginary parts of the wave function

\begin{equation*} \psi=\sum_m \left(c_m+id_m\right)e^{im\phi}e^{-im^2t} \end{equation*}

as well as the probability density $|\psi|^2\text{.}$

Activity 21.1.

Explore how the ring state is made up out of a linear combination of basis states.
