Waves Chapter 1
| Question | Answer |
|---|---|
| Energy that transfers energy from place to place | waves |
| Mechanical waves are created when a source of energy causes a medium to what | 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 |
| 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? | resonance |
| How do mechanical 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 | 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 interference |
| Why do you see lightning from a distant storm before you hear thunder? | light is faster than sound |
| Compressions and rarefactions are characteristic of what type of wave? | longitudinal |
| The distance between two consecutive crests of a wave is called the | wavelength |
| What is the top of the triangle | velocity |
| what is the bottom left of the triangle | waves |
| what is the bottom right of the triangle | frequency |
