| 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 | Vibrate |
| The speed of a wave is it's wavelength multiplied by it's | Frequency |
| The bending of a wave due to a change in speed is called | Refraction |
| The bending of a wave bending around the edge of a barrier is known as | Diffraction |
| The interaction between two waves that meet is called | interference |
| Waves combine to make a wave with 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 appears to be standing still, the result is a | standing wave |
| What occurs when vibrations travelling through an object match a the object's natural frequency? | resonance |
| A wave travels through a medium because | Energy passes from partical to partical |
| Mechanical waves are classified according to | motion |
| Frequency is measured in units called | Hertz |
| When a wave hits a surface through which it cannot pass and bounce back it undergoes | Reflection |
| Waves combine to produce a smaller or zero-amplitude wave in a process called | destructive interference |
| Why do you see lightning from a a distant storm before you hear thunder | Light travels faster than sound |
| compression and rarefaction are characteristic of what type of wave | longitudinal wave |
| the distance between two consecutive crest of a wave is called | wavelength |
