Waves

QuestionAnswer
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
16. The distance between two consecutive crests of a wave is called the wavelength
a. Rarefraction
b. Compresstion
c. Wavelength
f. crest
g. amplitude
j. wavelength
h. trough
1. Reflection
2. Dafraction
3. Destructive Interference
4. Constructive Interference
5. Refraction
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
