| Question | Answer |
|---|---|
| A Disturbance that transfers energy from place to place is called | Wave |
| Mechanical waves are created when a source of energy causes a medium to | Vibrate |
| The speed of a wave is its wavelength times its | Frequency |
| The bending of waves around an object is known as | Diffraction |
| The interaction of two waves that meet is | interfierence |
| waves combine too make a wave of larger amplitude through a process called | constructive interference |
| when an incoming wave combines with a reflected wave in such a way it appears to be standing still it is called | a standing wave |
| what occurs when vibrations travelling through an object mach that objects natural frequency | resonance |
| A wave travels through a medium because | energy travels from particle to particle |
| Mechanical waves are classified according to | wave motion |
| Frequency is measured in | Hertz |
| when a wave hits a surface which it cannot travel through it | Reflects |
| waves that combine to form a zero amplitude experience | Destructive interfirence |
| why do you see lighting before you hear thunder? | because light travels faster than sound |
| Compression's and rarefaction are characteristic of what wave type | longitudinal |
| the distance between two consecutive crests of a wave is called the | Wavelength |
| the bending of waves do to a change in speed is called | refraction |
