# Chapter 15 - Characteristics Of Waves

12 Questions | Total Attempts: 445  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?
• 2.
A.  What does arrow M indicate?b.  What does arrow N indicate?c.  What does the dotted line AB represent?d.  Which numbered angle represents the angle of incidence?e.  Which numbered angle represents the angle of reflection?f.  What does the line CAD represent?
• 3.
BONUS:  Describe the difference between constructinve and destructive interference.

• 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 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)
