Resonance Demonstrator: three mass-spring systems, each designed to have a specific natural frequency of oscillation. Rapid shaking of the base excites the middle mass in to large amplitude motion while the other two remain relatively motionless. Moving the base slowly excites the large mass, and shaking such that the rate is between these two frequencies excites the mass on the longer leaf spring. A demonstration of frequency response- how periodic forces of small amplitude can produce large am

Objects, mechanical systems and charged particles tend to vibrate at a specific frequency. We call this frequency the resonant frequency or the natural frequency. When a light or a sound wave strikes an object that is already vibrating at some particular frequency, and if that frequency happens to match the resonant frequency of the object it’s hitting; then you’ll get what’s called resonance. Resonance occurs when the matching vibrations of another object increase the amplitude of an object’s o
