Document Summary
A vibration is a periodic wiggle intime. A periodic wiggle in both space and time is a wave. Light and sound are both vibrations that propagate through space as waves. Vibration of a pendulum made visible on a moving conveyor belt by a pendulum swinging at right angles above the moving belt; a pictorial representation of a wave produced by simple harmonic motion. A long pendulum has a longer period than a short pendulum through which is swings. The amplitude equals the maximum displacement from equilibrium. A sine curve can be traced by a bob attached to a spring undergoing vertical harmonic. For a water wave, the high points of a sine wave are called crests and the low points are. The distance from the top of one crest to the top of the next crest. The time from one complete vibration. A wave in which the medium vibrates perpendicularly to the direction in which the wave travels.
