So that's what resonance essentially means. When we apply a repetitive (periodic) external force onto our system at exactly the right times, the system ends up oscillating, with higher and higher amplitude. In simple terms, a system undergoes "resonance" when an external driving force is applied at regular intervals, and at very specifically the "natural" or "resonant frequency" of the system. but how does it work? In this video we'll look at 4 examples that help us clarify what resonance is and how we've come to use it for our own benefit.ġ:42 - Example 1 - Playground Swing: What is Resonance?Ģ:46 - Example 2 - The Sarangi: Resonance in Musicħ:46 - Example 3 - Tacoma Narrows Bridge: Resonance, or Aeroelastic Flutter?Ĩ:47 - Example 4 - Resonance of Nanoparticles Using Lasers
