Chapter 1 Waves
Science 2019-20 Mr. Huizenga
| Term | Definition |
|---|---|
| Wave | a disturbance that transfers energy from place to place |
| Vibrates | mechanical waves are created when a source of energy causes a medium to |
| Frequency | the speed of a wave is its wavelength multiplied by its |
| Refraction | the bending of waves due to a change in speed |
| Diffraction | the bending of waves around the edge of a barrier is known as |
| Interference | the interaction between two waves that meet is called |
| Constructive Interference | waves combine to make a wave with larger amplitude in a process called |
| Standing Wave | when an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still, the result is a |
| It will vibrate | what occurs when vibrations traveling through an object match the object's natural frequency |
| It goes from particle to particle | a wave travels through a medium because |
| if it needs a medium | mechanical waves are classified according to |
| hertz | frequency is measured in units called |
| reflection | a wave hits a surface through which it CANNOT pass and bounces back |
| Destructive Interference | waves combine to produce a smaller or zero-amplitude wave in a process called |
| Light travels faster than sound | you see lightning from a distant storm before you hear thunder because |
| longitudinal | this wave has characteristics like rare-fractions and compressions |
| wavelength | the distance between two consecutive crests of a wave |
