The utility model discloses a visual interactive electromagnetic wave experiment teaching system comprises experiment platform subsystem, microwave receiving and dispatching subsystem, host computer / the next quick -witted operation controls subsystem, experiment platform subsystem is used for collecting the electromagnetic to be changed, microwave receiving and dispatching subsystem sends the electromagnetic wave and collects the electromagnetic wave change and spread into host computer / the next quick -witted operation controls subsystem into, host computer / the next quick -witted operation controls subsystem is used for handling the received electromagnetic wave to be changed and form images, still is used for control microwave receiving and dispatching subsystem to send the electromagnetic wave. The utility model discloses an effectively alleviate in the electromagnetic wave teaching electromagnetic wave and cannot see, can not touch the theory that causes and be hard to digestion, a great deal of difficulty that the theory is difficult to to intergrate with practice, through the visual mode interactive with the experimentation of electromagnetic wave, the experimental design class that can support shape is extensive, and the kind is various, and the form of expression is lively, can effectively arouse the independence and the consciousness of study, does benefit to knowledge learning and cultivates with the innovation ability.
