vibrations, waves, and sounds
| Term | Definition |
|---|---|
| Amplitude (volume) | For a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position. |
| Wavelength | The distance between successive crest, troughs, or identical parts of a wave |
| Frequency (pitch) | 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. |
| period | 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. |
| Period of a Pendulum | T=2(Pi)sqrt(L/g) |
| transverse wave | a wave in which the medium vibrates in a direction perpendicular to the direction in which the wave travels. |
| longitudinal wave | a wave in which the medium vibrates in a direction parallel to the direction in which the wave travels. |
| velocity formula | wavelength x frequency = speed V=FY (wavelength-Y)(frequency-F) |
| frequency formula | 1/period |
