| Question | Answer |
|---|---|
| A disturbance that transfers energy from place to place | waves |
| Mechanical waves are created when a source of energy causes a medium to | vibrate |
| The speed of a wave is is wavelength multiplied by its | frequency |
| The Bending of waves due to a change in speed is called | refraction |
| The interaction between two waves that meet is called | interference |
| The bending of waves around the edge of a barrier is known as | diffraction |
| Waves combine to make a wave with a larger amplitude in a process called | constructive interference |
| What occurs when vibrations traveling through an object match the objects natural frequency | resonance |
| A wave travels through a medium because | energy passes from particle to particle |
| When an incoming wave combines with the reflected 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 |
| Mechanical waves are classified according to | how they move |
| Frequency is measured in | Hertz |
| When a wave hits a surface witch it CANNOT pass through and bounces 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 before hearing the thunder? | light travels faster than sound |
| Compressions and rarefactions are characteristics of what kind of wave? | Longitudinal |
| The distance between 2 consecutive crests in a wave is called the | wavelength |
