When the thumb is the direction of current, the coiled fingers represent the direction of magnetic field around it.
When the coiled fingers are the current, as in a solenoid, then the thumb points north.

You just have to know the use of ripple tanks to demonstrate these properties of waves, diagrams representing them, changes in wavelength, speed, frequency (if any).....and be able to draw all of them. That's all =D
