Chapter 15 - Characteristics Of Waves
Settings
If you ask a room full of people to picture a wave, they might all think of something different – be it at the ocean, a soundwave, maybe even a person waving. Today we’ll be taking a look at the characteristics of waves, asking you a number of questions regarding how they work.
- 1.
![Answer these questions - make sure you label which is which!a. What does the person transfer to the rope by pulling it up and down at point A?b.
What does the direction of arrow B indicate?c.
In what direction does the medium move relative to the direction of the wave? Explain.d.
What kind of wave is being generated?e.
What does point C represent?f.
What is the medium through which the wave is moving?]( "Answer these questions - make sure you label which is which!a. What does the person transfer to the rope by pulling it up and down at point A?b.

- 3.BONUS: Describe the difference between constructinve and destructive interference.
- 4.All of the following are types of waves EXCEPT:
- A.
Transverse Waves
- B.
Sound Waves
- C.
Longitudinal Waves
- D.
Antinode Waves
- 5.The amplitude of a transverse wave is found by measuring the distance
- A.
Between two crests
- B.
Between two troughs
- C.
From rest position to a crest
- D.
From a crest to a trough
- 6.A longitudnal wave has a large amplitude if
- A.
The compressions are dense (close together)
- B.
The troughs are very low
- C.
There are no rarefactions
- D.
The crests are far apart
- 7.An example of a reflected wave is
- A.
An echo
- B.
A transverse wave
- C.
A tsunami
- D.
A surface wave
- 8.Constructive interference occurs when two waves
- A.
Are traveling in the same direction
- B.
Combine to make a wave with a larger amplitude
- C.
Change their speed and bend
- D.
Combine to make a wave with a smaller amplitude
- 9.Waves that require a medium to travel through are called _________________________ waves.
- 10.The highest part of a wave is called the ________________________.
- 11.The bending of waves around the edge of a barrier is known as _____________________.
- 12.In standing waves, the ____________________ are points with no amplitude. (the point where the rope does not appear to move)
