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 next illustrated, followed by a series of experiments using a klystron. The measurement of wavelengths is introduced by showing standing waves with the Vinycomb model, Sir Lawrence then illustrating the same principles by applying electromagnetic waves to Young's pinhole experiment.
I didn't know that... Never heard of that...
I asked about the prism because he used the shape to reflect the signal. If the signal hit the glass str8 on, will the signal split in half or be difussed like a rainbow?
So if you would have a radio signal consisting of many frequencies, it should be refracted accordingly and "spread/separate" like the rainbow.
