Wave Review
7th grade science
| Question | Answer |
|---|---|
| A disturbance that transfers energy from one place to a place is called a | wave |
| Mechanical waves are created when a source of energy causes a medium to | move |
| 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 objects natural frequency | residence |
| A wave travels through a medium because | energy is passed from particle to particle |
| Mechanical waves are classified according to | how they move |
| 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 interaction between two waves that meet is called | interference |
| Waves combine to make a wave with larger amplitude in a process called | constructive |
| The bending of waves around the edge of a barrier is known as | differaction |
| The bending of waves due to a change in speed is called | refraction |
| Frequency is measured in | hz (Hertz) |
| Wavelength is measured in | m (meters) |
| Frequency equals: | speed/wavelength |
| Wavelength equals: | speed/frequency |
| Speed equals: | wavelength times frequency |
| The speed of a wave is its wavelength multiplied by its | frequency |
| When a wave hits a surface through which it cannot pass and bounces back , it undergoes | reflection |
| The distance between two consecutive crests of a wave is called the | wavelength |
