chapter 1 waves
| Question | Answer |
|---|---|
| A disturbance that transfers energy from place to place is called a | medium |
| 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 is called | refraction |
| The bending of waves 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 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 appears to be standing still, the result is a | standing wave |
| What occurs when vibrations traveling through an object match the object’s natural frequency? | resonate frequency |
| How do mechanical waves travel through a medium? | Energy passes from particle to particle |
| Mechanical waves are classified according to | The medium that they go through and their movement |
| Frequency is measured in units called | hertz |
| 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 interference |
| Why do you see lightning from a distant storm before you hear thunder? | because light is faster then sound |
| Compression and rarefaction are characteristic of what type of wave? | longitudinal wave |
| The distance between two consecutive crests of a wave is called the | wavelength |
