DDES - Science - Waves
| Question | Answer |
|---|---|
| the distance between two crests of a transverse wave | wavelength |
| the number of waves that pass a given point in a certain amount of time | frequency |
| the part of a longitudinal wave where the particles of the medium are far apart | rarefraction |
| how quickly a wave moves through a medium | speed |
| the part of a longitudinal wave where the particles of the medium are close together | compression |
| the maximum distance that the particles of a medium move away from their rest position as a wave passes through the medium | amplitude |
| the bending of waves as they enter a different medium | refraction |
| the interaction between 2 or more waves that meet | interference |
| the increase in the amplitude of vibration that occurs when external vibrations match the object's natural frequency | resonance |
| a wave that apprears to stand in one place even though it is really two waves interfering as they pass each other | standing wave |
| the bending of waves around a barrier | diffraction |
| the bouncing back of a wave when it hits a barrier that it cannot pass through | reflection |
| occurs when a vibration causes air molecules to compress and rarify | sound wave |
| a sound wave is an example of this type of wave | longitudinal wave |
| waves on the ocean occur at the surface between these two things | air and water |
| an ocean wave is an example of this kind of wave | surface wave |
| the highest point of the wave | crest |
| the lowest point of the wave | trough |
| before the wave is disturbed | rest position |
| the unit used to measure frequency | hertz |
| a pencil appears broken when place in a beaker of water because light waves do this | refract |
| a wave that occurs at the surface of two mediums | surface wave |
| a disturbance that transfers energy from place to place | wave |
| the unit we use to measure wavelength | cm |
| the material through which a wave travels | medium |
| a wave that moves through a medium in a direction perpendicular to the direction in which the wave travels | transverse wave |
| a glass shattering because of a loud, steady sound wave is an example of this | resonance |
| an echo occurs when a sound wave does this | reflect |
