Oscillator
From Simple English Wikipedia, the free encyclopedia
An oscillator is something that "vibrates", or repeats the same pattern. Many things in nature move back-and-forth or up-and down when pushed or struck. In time, natural oscillators slow down and stop because of friction.
[edit] Examples
• The pendulum of a "grandfather clock", for example, is a very slow oscillator.
• The strings of pianos and string instruments "oscillate" when struck by a hammer.
• A water wave is the result of water moving up and down.
• Circuits powered by electricity can "oscillate". Such circuits can be used to make sounds or radio waves.
