Question | Answer |
---|---|
vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium | simple harmonic motion |
the maximum displacement from equilibrium | amplitude |
the time that it takes a complete cycle to occur | period |
the number of cycles or vibrations per unit of time | frequency |
a physical environment through which a disturbance can travel | medium |
a wave that requires a medium through which to travel | mechanical wave |
a wave whose particles vibrate perpendicularly to the direction the wave is traveling | transverse wave |
the highest point above the equilibrium position | crest |
the lowest point below the equilibrium position | trough |
the distance between two adjacent similar points of a wave, such as from crest to crest or from trough to trough | wavelength |
a wave whose particles vibrate parallel to the direction the wave is traveling | longitudinal wave |
a superposition of two or more waves in which individual displacements on the same side of the equilibrium position are added together to form the resultant wave | constructive interference |
a superposition of two or more waves in which individual displacements on opposite sides of the equilibrium position are added together to form the resultant wave | destructive interference |
a wave pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and interfere | standing wave |
a point in a standing wave that maintains zero displacement | node |
a point in a standing wave halfway between two nodes, at which the largest displacement occurs | antinode |
