Electromagnetic waves

Experiments and demonstrations on the nature of electromagnetic waves.

The nature of electromagnetic waves is demonstrated first with the aid of models and then by a reconstruction of Faraday’s experiment on induction. The range of electromagnetic waves is illustrated next, followed by a series of experiments using a klystron. The measurement of wavelengths is then introduced by showing standing waves with the Vinycomb model. Bragg finally illustrates the same principles by applying electromagnetic waves to Young’s pinhole experiment.
