Coulombic 1⁄r potential.	Stark - Coulomb potential for a Rydberg atom in a static electric field.	Trajectory of the of the electron in a hydrogen atom in an electric field $\scriptstyle {{\vec {E}}=-3\times 10^{6}{\hat {x}}}$ .	A Classical simulation of the trajectory and angular momentum of the electron in a hydrogen atom in an electric field $\scriptstyle {{\vec {E}}=-3\times 10^{6}{\hat {x}}}$ . <<Full size>>

Second order Stark shifts in hydrogen. Each n-level consists of n-1 degenerate sublevels; application of an electric field breaks the degeneracy.	A graphical representation of the complex impedance plane. Note that while reactance $\scriptstyle {\mathrm {X} }$ can be either positive or negative, resistance $\scriptstyle {R}$ is always positive.	An AC supply connected across a device with impedance $\scriptstyle {Z}$ , with an AC voltmeter and ammeter in parallel, and series respectively. An AC supply applying a voltage $\scriptstyle {V}$ across a load $\scriptstyle {Z}$ , driving a current $\scriptstyle {I}$ .	Voltage and current phases for an ideal capacitor and inductor.

	An adiabatic process. Change in the probability density of a ground state quantum harmonic oscillator, due to an adiabatic increase in spring constant.	An avoided energy level crossing in a two level system subjected to an external magnetic field.	Repulsive force between two negatively charged lengths of tape.

Attractive force between two oppositely charged lengths of tape.	Fine and hyperfine structure in hydrogen. Not to scale.
