Con Physics Ch. 19 Vibrations and Waves
Terms in this set (16)
The waveform traced by simple harmonic motion, which can be made visible on a moving conveyor belt by a pendulum swinging at right angles above the moving belt.
For a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position
The distance between successive crests, troughs, or identical parts of a wave.
For a vibrating body or medium, the number of vibrations per unit. For a wave, the number of crests that pass a particular point per unit time.
The SI unit of frequency. One hertz equals one vibration per second.
The time in which a vibration is completed. The period of a wave equals the period of the source and is equal to 1/ Frequency.
A wave in which the medium vibrates perpendicularly to the direction in which the wave travels. Light waves and waves on stringed instruments are transverse.
A wave in which the medium vibrates parallel to the direction in which the wave travels. Sound waves are longitudinal.
The speed with which waves pass a particular point: Wave speed = frequency * wavelength
The phenomenon that occurs when two waves meet while the traveling along the same medium.
The pattern formed by the superposition of different sets of waves that produces reinforcement in some places and cancellation in others.
A stationary interference pattern formed in a medium when two sets of identical waves pass through the medium in opposite directions
The shift in received frequency due to the motion of a vibrating source toward or away from a receiver.
The V-Shaped disturbance created by an object moving across a liquid surface at a speed greater than the wave speed.
The cone-shaped disturbance created by an object moving at supersonic speed through a fluid.
The loud sounds that results from the incidence of a shock wave.
