Definition
| The waveform traced by simple harmonic motion, which can be made visible on a moving coveyor belt by a pendulum swinging at right angles above the moving belt. |
|
|
Term
|
Definition
| for a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position. |
|
|
Term
|
Definition
| the distance between successive crests, troughs, or identical parts of waves. |
|
|
Term
|
Definition
| for a vibrating body or medium, the number of vibrations per unit time. For a wave, the number of crests that pass a particular point per unit time. |
|
|
Term
|
Definition
| The SI unit of frequency. One hertz (symbol Hz) equals one vibration per second. |
|
|
Term
|
Definition
| 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. |
|
|
Term
|
Definition
| The speed with which waves pass a particular point. |
|
|
Term
|
Definition
| Awave in which the medium vibrates in a direction perpindicular to the direction in which the wave travels. Light waves and water waves are transverse. |
|
|
Term
|
Definition
| a wave in which the medium vibrates in a direction parallell (longitudinal) to the direction in which the wave travels. sound waves are longitudinal. |
|
|
Term
|
Definition
| The pattern formed by superposition of different sets of waves that produces reinforcement in some places and cancellation in others |
|
|
Term
|
Definition
| a stationary wave pattern formed in a medium when two sets of identical waves pass through the medium in opposite directions. |
|
|
Term
|
Definition
| the shift in recieved frequency due to motion of a vibrating source toward or away from a reciever. |
|
|
Term
|
Definition
| the V shaped disturbance created by an object moving across a liquid surface at a speed greater than the wave speed |
|
