| Question | Answer |
|---|---|
| A disturbance that transfers energy from place to place is called | a wave |
| Mechanical waves are created when a source of energy causes a medium to | move |
| The speed of a wave is its wavelength multiplied by its | frequency |
| The bending of waves due to a change in speed called | refraction |
| The bending of waves around the edge of a barrier is known as | difference |
| The interaction between two waves that meet is called | interference |
| Waves combine to make a wave with a larger amplitude in a process called | constructive interference |
| When an incoming wave combines with a reflected wave in such a way that the combined wave seems to be standing still, the result is a | standing wave |
| What occurs when vibrations traveling through an object match the objects natural frequency? | resonance |
| How do mechanics waves travel through a medium? | energy passes from particle to particle |
| Mechanical waves are classified according to | how they move |
| Frequency is measured in units called | hertz/hz |
| When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes | reflection |
| Waves combine to produce a smaller or zero-amplitude wave in a process called | destructive inerference |
| Why do you see lightning from a distant storm before you hear thunder? | light travels faster than sound |
| Compressions and rarefactions are characteristics of what type of wave? | longitudinal |
| The distance between two consecutive crests of a wave called the | wavelength |
