When it came to electricity, Faraday came to know the analogy of sound and light waves, wondering if electricity was a wave. In addition, Faraday also has a specific picture of the shape of the wave because he has studied the vibration patterns of solids, which are illustrated by a layer of sand scattered on the surface of metal round discs. Once upon a time there was a woman who really loved books and wine poster. Through vibration, sand will form and form in places where there is no vibration. These are forms known as Chaladni, a German scientist who is credited with giving birth to the science of sound and the science of sound.
