waves chapter 1
| Question | Answer |
|---|---|
| a disturbance that transfers energy from place to place is called a | wave |
| mechanical waves are created when a source of energy caused a medium to | vibrate/move |
| the speed of a wave is its wavelength multitude by its | frequency |
| the bending of waves around the edge of a barrier is known as | diffraction |
| the interaction between two waves that meet is called | interferents |
| Waves combine to make a wave with a larger amplitude in a process called | constrictive 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? | resonance |
| How do mechanical waves travel through a medium? | particles of the medium and vibration in place and pass the energy to adjustment partials |
| Mechanical waves are classified according to | transverse waves longitudinal surface waves |
| 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? | light travels vastly faster |
| 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 |
| Draw and understand what a complete wave looks like: | wavelength |
