Characteristics of Waves
| Question | Answer |
|---|---|
| Wave | A disturbance that transfers energy from place to place. |
| Medium | Material through which a wave travels |
| Transverse | Waves that move the medium at right angles to the direction of the wave |
| Longitudinal | Waves that move the medium parallel to the direction of the wave |
| Crest | The highest part of a transverse wave |
| Trough | The lowest part of a transverse wave |
| Compression | The part of a longitudinal wave where the particles of closer together |
| Rarefaction | The part of a longitudinal wave where the particles are farther apart. |
| Amplitude | The maximum distance that the particles of the medium move from their rest position |
| Wavelength | The distance between two corresponding parts of a wave |
| Frequency | The number of complete waves that pass by a given point in a certain amount of time |
| Hertz | Unit for frequency |
| Sound | A disturbance that travels through a medium as a longitudinal wave |
| Loudness | Your perception of the energy of a sound. It depends upon the amplitude of a sound wave and the distance from the source. |
| Pitch | A description of how high or low a sound seems to a person. It depends upon the frequency of a sound. |
| Mechanical | Waves that require a medium through which to travel |
| Visible Light | Electromagnetic waves that humans can see |
| White Light | A mixture of all the colors of visible light |
| Transparent | Material that transmits most of the light that strikes it |
| Translucent | Material that scatters light as it passes through |
| Opaque | Material that reflects or absorbs all of the light that strikes it |
| Convex | A lens that is thicker at the center and thinner at the edges |
| Concave | A lens that is thicker at the edges and thinner at the center |
| Reflection | When a wave hits a surface and it bounces back |
| Refraction | When a wave enters a new medium at an angle, causing the wave to bend |
