Design a physics problems (with numbers and can be
solved) related to electric, circuits, magnetic field,
electric field, wave (light, sound, diffraction) and has real world
context (chirstmas light, iron, cost of electric bills, rainbow,
magnet....). The problem needs to include a background information.
The situation is "rich" enough to need a picture drawn. The physics
scenario is more challenging that just plugging numbers into one of
the equations.
- The problem needs to come from a real world context...
