| amplitude |
greatest distance from crest of a wave |
| crest |
hight point of a wave |
| diffraction |
bending of waves around the edge of an obstacle |
| electromagnetic wave |
wave that consists of electric and magnetic fields and does not require a medium to exist |
| frequency |
number of waves that pass a certain point in a given amount of time |
| interference |
interaction of waves that occur at the same place at the same time |
| longitudinal wave |
wave in which the motion of the medium is parallel to the direction of the wave |
| mechanical wave |
a wave that disturbs a medium |
| medium |
material through which a mechanical wave travels |
| reflection |
bouncing back of waves upon reaching another surface |
| refraction |
bending of waves due to a change in speed |
| resonant frequency |
frequency at which a standing wave occurs |
| standing wave |
wave that does not appear to be moving, occurs at the natural frequency of the material |
| surface wave |
wave that consists of transverse and longitudinal waves and occurs at the surface between two different mediums |
| transverse wave |
wave in which the motion of the medium is at right angles to the direction of the wave |
| trough |
lowpoint of a wave |
| vibration |
movement that follows the same path over and over again |
| wave |
