If you take a hammer and bang it on the side of a building, do you think you can bring the building down? If you adjust a radio beam to the correct frequency, do you think you can destroy a nasty disease causing microorganism? Do you think all radio waves are harmful to human beings? These are some of the questions dealt with in this podcast. We take a look at inventors and researchers form the past and look at what frequencies and resonances can do.
In science if we give energy to a body, it will resonate for a long time. This is why soldiers crossing a bridge are ordered NOT to march in unison. They walk across the bridge “normally” because they know if they “march” across it, the bridge might come down. This is because of “resonances” created by the men marching. If you bang on a bell, it will “ring” for a long time. If you stroke a wine glass with a wet finger, the wine will have ripples along the surface. These are all resonances, or “standing waves.”
Do resonances have anythin
