Question | Answer |
1. A disturbance that transfers energy from place to place is called | wave |
2. Mechanical waves are created when a source of energy causes a medium to | move |
3. The speed of a wave is its wavelength multiplied by its | frequency |
4. The bending of waves due to a change in speed is called | Refraction |
5. The bending of waves around the edge if a barrier is known as | Diffraction |
6. The interaction between two waves that meet is called | Interference |
7. Waves combine to make a wave with larger amplitude in a process called | Constructive |
8. 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 |
9. What occurs when vibrations traveling through an object match the object's natural frequency? | Residence |
10. A wave travels through a medium because | The energy passes from particle to particle. |
11. Mechanical waves are classified according to | How they move or movement |
12. Frequency is measured in units called | Hertz |
13. When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes | Reflection |
14. Waves combine to produce a smaller or zero-amplitude wave in a process called | Destructive Interference |
14. Why do you see lightning from a distant storm before you hear thunder? | Light travels faster than sound. |
15. Compresstions and rarefactions are characteristics of what type of wave? | Longitudinal Wave |

a. | Rarefraction |
b. | Compresstion |
c. | Wavelength |
f. | crest |
g. | amplitude |
j. | wavelength |
h. | trough |
1. | Reflection |

1. What is the Frequency of the wave above in Hertz? | w/s 3/3=1hz |
2. A wave with a frequency of 10 Hz has a wavelength of 5 meters. At what speed will this wave travel? | s=fy 10 Hz5meters=50 meters |
3. The speed of a wave is 40 m/sec. If the wavelength of the wave is 5 meters, what is the frequency of the wave? | f=s/y 40m/sec/s meters=8y |
4. A wave has a frequency of 20 Hz and velocity of 10 m/s. What is the wavelength of this wave? | y=s/f 10 m/s/ 20 Hz=0.5 meters |
