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 |
