Question | Answe |
---|---|
Natural Resonance | Energy in an isolated system of objects that causes it to preform the same motion over and over again. |
Oscillation | Restoring forces that result in a repeating motion. |
Period | The time it takes to complete one full cycle of an oscillation. |
Harmonic Oscillator | Restoring forces are proportional to its displacement from equilibrium. |
Anharmonic Oscillator | Restoring forces cease to be equal to its displacement from equilibrium. |
Hertz | cycle per second/ SI unit of frequency. |
Pitch | Frequency of a sound. |
Fundamental Vibrational Node | When the strong arcs completely one way and then the other, the center of the strong travels the furthest, and maximum potential and kinetic energy is reached. |
Mechanical Wave | Created through artificial means. (Music) |
High Order of Vibrational Modes | String vibrates as a chain of shorter strings arching in alternate directions. |
Superposition | When waves stand on top of one another. |
Resonant Energy Transfer | When modest force does work in synchronicity with natural resonance. |
Longitudinal Wave | Wave in which the underlying oscillation is parallel to the wave itself. |
Traveling Waves | Waves that move steadily in a particular direction. |
Dopler Effect | When the frequency of sound shifts because of a change in distance between the source and where is being heard. |
Dispersion | When wave length is dependent on speed. |
Refraction | Water shallows when a wave changes direction. |
Reflection | When a wave bounces off a wall such as a cliff or dock. |
Interference | Waves overlap each other. |
Constructive Interference | Waves work together to create immense crests or troughs. |
Destructive Interference | Waves lack crests of trough because they interfere with one another. |
