Sympathetic Resonance: mechanical energy is transmitted from one vibrating tuning fork to the other via sound- as revealed by a wood bead on a string. A beautiful example of resonance phenomena where tiny periodic accelerations (such as sound waves) can produce much larger scale accelerations and displacements if the frequency matches the natural frequency (or an overtone) of the structure. This set of tuning forks are manufactured to vibrate at the same frequency and are mounted on resonating c

🌎 Schumann resonance is the Earth’s natural electromagnetic frequency around 7.83 Hz. It’s often called the “heartbeat of the Earth.” ⁣⁣⁣Some believe that connecting with this resonance through practices like grounding can have positive effects on us.⁣⁣⁣ #schumannresonance #grounding #reinhardstanjek #ascensiontools #treehugging | Reinhard Stanjek - Ascension Tools

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
